We show for the first time enzyme-directed assembly of intravenously (IV) delivered nanoparticles in ischemic skeletal muscle, which has applications for drug delivery to damaged muscle of the type prevalent in peripheral artery disease (PAD). Altering the surface charge of the nanoparticles through addition of zwitterionic near-infrared dye species allowed for noninvasive in vivo imaging (IVIS) particle tracking and resulted in improved targeting to the ischemic muscle over healthy muscle. This has implications for noninvasive drug delivery vehicles for treating ischemic muscle, as no minimally invasive, non-surgical options currently exist.

Congratulations to our defending champions Clare, Sarah, and Swagat for successfully earning their PhD's!

In this study, we demonstrate that cationic polymers end-labelled with a Re(I) fac-tricarbonyl bipyridine electrocatalyst exhibit a significantly lower potential for CO2 reduction to CO (ca. 300mV) while neutral polymers behave consistently with what has been reported for the free, molecular catalyst. These materials may be useful as polymer-based precursors for preparing catalytic and highly ordered structures such as thin films, porous catalytic membranes, or catalytic nanoparticles.

We describe a method for the stabilization of low-boiling point (low-bp) perfluorocarbons (PFCs) at physiological temperatures by an amphiphilic triblock copolymer which can emulsify PFCs and be cross-linked. After UV-induced thiol-ene cross-linking, the core of the PFC emulsion remains in liquid form even at temperatures exceeding their boiling points. Critically, the formulation permits vaporization at rarefactional pressures relevant for clinical ultrasound.

Our manuscript in ACS Nano entitled "Bio-inspired Structural Colors Produced via Self-Assembly of Synthetic Melanin Nanoparticles" has reached 14753 downloads as per ACS ChemWorx. This innovative study was inspired by nature’s extensive use of self-assembled melanosomes to produce colors in avian feathers. Polydopamine-based synthetic melanin nanoparticles were fabricated as colored films. We demonstrated that the unique optical properties of synthetic melanin nanoparticles provide advantages for structural colors over other polymeric nanoparticles (i.e., polystyrene colloidal particles).

[October, 2016]

We describe a synthetic method for increasing and controlling the iron loading of synthetic melanin nanoparticles and use the resulting materials to perform a systematic quantitative investigation of the structure-property relationship of synthetic melanin. A comprehensive analysis by magnetometry, electron paramagnetic resonance (EPR), and nuclear magnetic relaxation dispersion (NMRD) reveals the complexities of the magnetic behavior and how these intraparticle magnetic interactions manifest in useful material properties such as their performance as MRI contrast agents. This analysis allows predictions of the optimal iron loading through a quantitative modeling of antiferromagnetic coupling that arises from proximal iron ions. This study provides a detailed understanding of this complex class of synthetic materials and gives insight into interactions and structures prevalent in naturally occurring melanins.

Here, we show for the first time fast, significant, and reversible changes of structural coloration in self-assembled SMNP films in response to changes in humidity. This process is driven by the hygroscopic nature of the particles, leading to changes in the thickness of the SMNP layer that alter the interference color. This mechanistic explanation is supported by water absorption measurements, an optical model, and environmental scanning electron microscopy. Humidity-induced dynamic colors arising from SMNP films offer possible routes for synthetic melanin as an important material in sensors and coatings.

Fluorocarbon (FC) modified polyethylenimine (PEI) were synthesized for the purpose of siRNA delivery. Compared to hydrocarbon (HC) analogues, the FC vectors showed greater general silencing efficacy, higher cell uptake, and reduced association with serum components. Collectively, the data suggest that modification of polyamines with FCs is a promising approach for the discovery of novel vectors for siRNA delivery.

The synthesis of functional polymers encoded with biomolecules has been an extensive area of research for decades. The greatest impact of this work has been in biomedicine and biotechnology, where fully synthetic and naturally derived biomolecules are used cooperatively. Despite significant improvements in biocompatible and functionally diverse polymers, our success in the field is constrained by recognized limitations in polymer architecture control, structural dynamics, and biostabilization. This Perspective discusses the current status of functional biosynthetic polymers and highlights innovative strategies reported within the past five years that have made great strides in overcoming the aforementioned barriers.

Congratulations to Lucas Parent for recieving the National Institutes of Health Ruth L. Kirschstein National Research Service Award (NRSA) Individual Postdoctoral Fellowship (Parent F32). The purpose of the this fellowship is to enhance the research training of promising postdoctoral candidates who have the potential to become productive, independent investigators in scientific health-related research fields relevant to the missions of the participating NIH Institutes and Centers.

Direct polymerization of an oxaliplatin analogue was used to reproducibly generate amphiphiles in one pot, which consistently and spontaneously self-assemble into well-defined nanoparticles (NPs). We investigated cellular uptake pathways, intracellular release, and resulting cytotoxicity combinatorial super-resolution fluorescence structured illumination microscopy (SIM) and nanoscale secondary ion mass spectrometry (NanoSIMS). We contend this type of combined optical and isotopic imaging strategy represents a powerful and potentially generalizable methodology for cellular tracking of nanocarriers and their cargo.

Amphiphilic block copolymers, with hydrophilic blocks composed entirely of norbornenyl linked Gd3+-coordinated analogues of the MRI contrast agent Gd-DOTA, were assembled into spherical- or fibril-nanoparticles that both demonstrated enhanced relaxivity over Gd-DOTA. As an initial examination of their behavior in vivo, intraperitoneal (IP) injection of NPs into live mice was performed, showing long IP residence times, observed by MRI. Extended residence times for particles of well-defined morphology may represent a valuable design paradigm for treatment or diagnosis of peritoneal malignances.

We report the development of cryogenic transmission electron microscopy where laboratory generated sea spray aerosol particles are flash frozen in their native state with iterative and controlled thermal and/or pressure exposures and then probed by electron microscopy. This unique approach allows for the detection of not only mixed salts, but also soft materials including whole hydrated bacteria, diatoms, virus particles, marine vesicles, as well as gel networks within hydrated salt droplets—all of which will have distinct biological, chemical, and physical processes.

Congratulations to Cassi Callmann for recieving the Inamori Fellowship. The Inamori Fellowship is intended to support UCSD's best and brightest graduate students who will ensure the future of humanity through the balance of the scientific process and the human spirit. This fellowships was established by the Inamori Foundation through a generous grant to the Division of Physical Sciences.

The micelle blending protocol is expanded to a range of polymer micelle systems and self-assembly routes. By exploring a range of variables, it was found that the systems must be able to reach global equilibrium at some point for the blending protocol to be successful. The results demonstrate the kinetic requirements, specifically core block glass transition temperature, Tg, and length of the block limiting the exchange rates, for the blending protocol which can then be applied to a wide range of polymer systems to access this simple protocol for polymer self-assembly.

In an unprecedented example, in situ transmission electron microscopy (TEM) was used as a viable approach for imaging the motion of organic, polymeric soft nanoparticles in liquid water. In this case, particles were studied which were obtained from the direct polymerization of an oxaliplatin analog, designed for an ongoing program in novel chemotherapeutic delivery systems. This technique is expected to become essential in the characterization of analogous systems, especially where dynamics are of interest in the solvated state.

Micellar nanoparticles were designed to be responsive to matrix metalloproteinases (MMPs) and reactive oxygen species (ROS), each of which is upregulated in the pathology of inflammatory diseases. The amphiphilic polymer-based nanoparticle system consists of a hydrophilic shell responsible for particle morphology change and aggregation, together with a hydrophobic block designed to release cargo in the presence of ROS.

Herein, we describe a simple and potentially widely applicable solution involving the polymerization of a minimally modified amino acid sequence (inclusion of a single Arg or Lys and a norbornenyl unit) into a high density brush polymer. The brush polymer of a known therapeutic peptide, which does not penetrate cells on its own, proficiently entered cells while maintaining its intracellular function. We anticipate that this methodology will find broad use in medicine, increasing or enabling the in vivo efficacy of promising peptide therapeutics.

This work describes amphiphilic tri-block copolymers containing FeIII-catecholate complexes formulated as spherical- or cylindrical-shaped micellar nanoparticles as new T1-weighted gadolinium-free imaging agents with high relaxivity, low cytotoxicity, and long-term stability in biological fluids. Compared with recently reported natural or synthetic melanin-based T1 agents, our approach utilizes well-defined tri-block copolymers prepared via a controlled living polymerization method. This synthetic route gives access to a tunable polymer system and hence, differently shaped self-assembled nanoparticles with controlled physical parameters.

A strategy for PLA functionalization that establishes the preparation of highly derivatized materials in which ring opening metathesis polymerization (ROMP) is employed as a graft-from polymerization technique utilizing a norbornene-modified handle incorporated into the PLA backbone. As a demonstration of this new synthetic methodology, a PLA-derived nanoparticle whose morphology could be controllably altered in response UV light exposure or acidic pH was produced. We anticipate that this graft-from approach to derivatization of PLA could find broad use in the development of modified, biodegradable PLA-based materials.

[September, 2015]

Norbornenyl cyclic elastin-like peptides were polymerized via ring opening metathesis polymerization (ROMP) to generate thermally responsive brush polymers. The nature of the thermal response depends on whether the side-chain peptides are cyclic, or linear, and can therefore be modulated using enzymes to cleave the peptide.

As an effort toward amplifying nanoscopic or microscopic responses, we developed biologically active peptide polymer amphiphiles (PPAs), which incorporate biphenyl mesogens capable of organizing within liquid crystalline (LC) phases. Rational design of this system permits the detection of biomolecular events (i.e. enzyme cleavage) due to LC ordering transitions in PPA-coated LC microdroplets. This work establishes a potentially modular approach for detecting a range of biomolecular events, wherein the composition of PPA and interactions between PPAs and co-surfactants can be tailored to induce changes in LC geometries.

This work represents a proof-of-concept method for targeting and retaining intravenously injected nanoparticles at the site of acute myocardial infarction (MI). Enzyme-responsive peptide-polymer nanoparticles undergo infarct-induced assembly directly at sites of damaged heart tissue. This delivery strategy combines the separate advantages of non-invasive particle delivery and prolonged scaffold retention currently desired for biomaterials use in cardiovascular disease treatment.

In this work, we probed the temperature dependent encapsulation efficiency of high-Tg polynorbornene micelles using the hydrophobic dye, BODIPY. We report the longest ever recorded triplet lifetime for BODIPY at room temperature, which is attributed to the hindered triplet-triplet annihilation in the high-viscosity micellar shell. This method provides an effective replacement for traditional pyrene assays in assessing the ability of norbornene-based micelles to act as nanocarriers for noncovalently loaded hydrophobic drugs, to probe the local core-shell environment, and to measure the critical micelle concentration (CMC).

The group published the first demonstration of the delivery of therapeutics to tumors using the enzyme-directed assembly of a responsive nanoparticle. This targeting approach represents a significant departure from known methods of active or passive targeting to tumors. We anticipate the strategy will be generally useful for the delivery of therapeutics and diagnostics to tumors where high levels of inflammation-associated proteases are present. For example, in the case of metastatic tumor tissues.
