- Abstract:
- ... Stimuli-responsive and biodegradable polymeric carriers are of great importance for safe delivery and efficient release of chemotherapeutic agents. In this work, given the unique advantages of poly(disulfide)s and biodegradable polyphosphoesters, we designed and constructed a reduction-sensitive amphiphilic triblock copolymer poly(ethyl ethylene phosphate)-b-poly(disulfide)-b-poly(ethyl ethylene p ...

- Abstract:
- ... Photodynamic therapy (PDT) is a promising treatment against multiantibiotic-resistant bacteria with the advantage of a low tendency towards antibiotic resistance. Due to their high PDT efficiencies and superior chemical stabilities, fullerenes have been proposed as effective photosensitizers for the photodynamic inactivation of bacteria. However, the biomedical applications of fullerenes are hinde ...

- Abstract:
- ... The efficacy of nucleic acid therapies can be limited by unwanted degradation. Chemical modifications are known to improve nucleic acid stability, but the (i) types, (ii) positions, and (iii) numbers of modifications all matter, making chemically optimizing nucleic acids a combinatorial problem. As a result, in vivo studies of nucleic acid stability are time consuming and expensive. We reasoned th ...

Here, we describe an approach for imparting near infrared (NIR) light-triggered release to pre-formed liposomes, using a newly-synthesized cationic, amphiphilic phthalocyanine. When simply mixed in aqueous solution with cargo-loaded liposomes, the cationic a ...

- Abstract:
- ... Bioelectronic platforms can be used for electrophysiology, monitoring and stimulating specific cellular functions. While planar electroactive materials have been extensively used, in the past decade new approaches have focused on engineering the interface with pseudo-3D micro and nanostructures and, more recently, on 3D geometries (i.e. scaffold-like). Here, we present an overview of this transiti ...

Sufficient and sustained anti-thrombogenicity is essential for blood-contacting materials because blood coagulation and thrombosis caused by platelet adhesion and activation on material surfaces may lead to functional failure and even fatal outcomes. Covalently conjugating anti-thrombogenic moieties into a polymer, instead of surface modification or blending, can maintain the anti-thrombogenicity ...
