Application

Biocompatible, amphiphilic block copolymer composed of a hydrophilic PEG block and a hydrophobic Poly(lactide-co-glycolide) (PLGA) block, functionalized with a terminal carboxylic acid. These materials have been used in control release and nanoparticle formulation for drug delivery applications. Well-defined materials with varying properties can be prepared by controlling the relative length of each polymer block. Additionally, the ratio of lactide to glycolide can be tuned to control rate of degradation. Carboxylic acid termination allows for facile further chemical modification of these materials.

Therapeutic nanoparticles (TNPs) aim to deliver drugs more safely and effectively to cancers, yet clinical results have been unpredictable owing to limited in vivo understanding. Here we use single-cell imaging of intratumoral TNP pharmacokinetics and pharmacodynamics to better comprehend their

Nitroglycerin (NTG) markedly enhances nitric oxide (NO) bioavailability. However, its ability to mimic the anti-inflammatory properties of NO remains unknown. Here, we examined whether NTG can suppress endothelial cell (EC) activation during inflammation and developed NTG nanoformulation to simultaneously amplify
