Gold (Au) nanoparticles have tunable optical and electronic properties and are used in a number of applications including photovoltaics, sensors, drug delivery & catalysis.
The world of commercial biomaterials has stagnated over the past 30 years as few materials have successfully transitioned from the bench to clinical use. Synthetic aliphatic polyesters have continued to dominate the field of resorbable biomaterials due to their long
The use of hydrogel-based biomaterials for the delivery and recruitment of cells to promote tissue regeneration in the body is of growing interest. This article discussed the application of hydrogels in cell delivery and tissue regeneration.
Polyethylene glycol (PEG) reagents offer numerous favorable characteristics, including high water solubility, high mobility in solution, lack of toxicity and immunogenicity, and ready clearance from the body.
The immune system protects the body from disease by resisting the invasion of foreign molecules into its cells, for example peptides and proteins are hydrolyzed by proteolytic enzymes; nucleic acids are hydrolyzed by nucleases; and most small molecules are eliminated
Aliphatic polyesters such as polylactide, poly(lactide-co-glycolide) and polycaprolactone, as well as their copolymers, represent a diverse family of synthetic biodegradable polymers that have been widely explored for medical uses and are commercially available.
The critical micelle concentration (CMC) can be approximately defined as the lipid monomer concentration at which appreciable amounts (>5% of total) of micellar aggregates first begin to appear in the equilibrium: nM1Mn
Poly(2-oxazoline)s (POx) can be viewed as conformational isomers of polypeptides. They are synthesized via living cationic ringopening polymerization (LCROP) of 2-oxazolines and were almost simultaneously discovered in 1966 by the groups of Litt, Tomalia, Fukui and Seeliger.
Professor Yoshiki Katayama (Kyushu University, Japan) discusses recent advances in drug delivery systems and strategies that exploit the EPR effect, with a special focus on stimuli-responsive systems based on novel materials.
Microparticle drug delivery systems have been extensively researched and applied to a wide variety of pharmaceutical and medical applications due to a number of advantages including injectability, local applicability to target tissues and sites, and controlled drug delivery over a
Our highly fluorescent iron oxide incorporated conjugated polymer nanoparticles (CPNs) have an iron oxide and semiconductor light emitting polymer core, encapsulated within a biocompatible surfactant.
