We report the preparation of a non-polymer coated superparamagnetic nanoparticle that is stable and biocompatible both in vitro and in vivo. The non-polymer, betaine, is a natural methylating agent in mammalian liver with active surface property. Upon systemic administration, the nanoparticle has preferential biodistribution in mammalian liver and exhibits good reduction of relaxivity time and ...

We report a facile and general strategy for enhancing the photostability of organic fluorophores for bioimaging applications. As a proof of concept, bright and robust fluorescence was observed in solid states of a well-defined synthetic polymer polycaprolactone consisting of di(thiophene-2-yl)-diketopyrrolopyrrole covalently linked in the middle of the polymer chain as a biocompatible and biore...

Anterior cervical discectomy and fusion (ACDF) has been performed for degenerative and traumatic cervical diseases to improve pain and neurologic symptoms including sensory change and motor weakness. Infection, however, is a rare complication of ACDF, and late infection is even much rarer. We present a case of late Infection from ACDF C4-5 using Biocompatible Osteoconductive Polymer (BOP) after...

Uniform polymer microbeads with highly loaded quantum dots (QDs) are produced using high-throughput coherent jet breakup of a biocompatible poly(ethylene glycol) diacrylate (PEGDA) prepolymer resin, followed by in-line photopolymerization. A spiraling and gradually widening channel enables maximum absorption of radiated UV light for the in-line photopolymerization without coalescence and cloggi...

DNA origamis are fully tailored, programmable, biocompatible and readily functionalizable nanostructures that provide an excellent foundation for the development of sophisticated drug-delivery systems. However, the DNA origami objects suffer from certain drawbacks such as low cell-transfection rates and low stability. A great deal of studies on polymer-based transfection agents, mainly focusing...

Short peptide substrates with high specificity toward transglutaminase (TGase) enzyme were designed, characterized, and coupled to a biocompatible polymer, allowing for rapid enzymatic cross-linking of peptide-polymer conjugates into hydrogels. Eight acyl acceptor Lys-peptide substrates and three acyl donor Gln-peptide substrates were rationally designed and synthesized. The kinetic constants o...
