Bioblends are composites of at least one biodegradable polymer with nonbiodegradable polymer. Successful development of bioblends requires that the biodegradable polymers be compatible with other component polymers. Compatibility can be assessed by evaluating the intermolecular interactions between the component polymers. In this work, the interaction in binary bioblends comprising biodegradabl...

The development of antibacterial drugs to overcome various pathogenic species, which inhabit the oral cavity, faces several challenges, such as salivary flow and enzymatic activity that restrict dosage retention. Owing to their amphipathic nature, antimicrobial peptides (AMPs) serve as the first line of defense of the innate immune system. The ability to synthesize different types of AMPs enabl...

Regenerative medicine is an exciting field that aims to create regenerative alternatives to harvest tissues for transplantation. In this approach, the delivery of cells and biological molecules plays a central role. The scaffold (synthetic temporary extracellular matrix) delivers cells to the regenerative site and provides three-dimensional environments for the cells. To fulfil these functions,...

CONTEXT The efficacy and safety of drug-eluting stents compared with bare-metal stents remains controversial in patients with ST-segment elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). OBJECTIVE To compare stents eluting biolimus from a biodegradable polymer with bare-metal stents in primary PCI. DESIGN, SETTING, AND PATIENTS A prospectiv...

We report the preparation of biodegradable nanoscopic hydrogels and their application for targeted drug delivery. The nanogel is synthesized in a template-free method by photo-crosslinking salt-induced polymer assemblies. With convenient incorporation of targeted lactosyl moieties, the nanogels efficiently deliver doxorubicin to HepG2 cells through receptor-mediated internalization.

A novel method is developed for template assisted fabrication of a regular assembly of microcavity arrays. Simple micropatterns on PDMS mold are used to create complex geometries via solvent vapor back pressure in a biodegradable polymer. Cavities are in turn replicated in complimentary PDMS mushroom like microstructures.

This communication describes a single-step electrospraying technique that generates core-shell microspheres (CSMs) with encapsulated protein as the core and an amphiphilic biodegradable polymer as the shell. The protein release profiles of the electrosprayed CSMs showed steady release kinetics over 3 weeks without a significant initial burst.

Bioresponsive polymeric nanoparticles have been extensively pursued for the development of tumor-targeted drug delivery. A novel redox-sensitive biodegradable polymer with "trimethyl-locked" benzoquinone was synthesized for the preparation of paclitaxel-incorporated nanoparticles. The synthesized redox-sensitive nanoparticles released paclitaxel in response to chemically triggered reduction.

Biodegradable polymers have attracted a lot of attention in the recent years. These biopolymers are large macromolecules composed of single, repeating monomer units. They are of very high molecular weight and their material characteristics vary according to the nature of their monomer composition. Over the last decade, depletion in the petroleum reserves has resulted in the emergence of biodegr...

We announce here the draft genome sequence of Halomonas hydrothermalis MTCC 5445, a halophilic bacterium of the class Gammaproteobacteria. It was isolated from the sea coast of Aadri, Veraval, Gujarat, India. Its genome contains genes for polyhydroxybutyrate (PHB), a biodegradable polymer that can be used as a substitute for petroleum plastics.
