Characterization with dynamic light scattering, zeta-potential analysis and scanning electron microscopy showed that the microcapsules had a mean particle diameter of 381.2 nanometres, a polydispersity index of 0.574 and a zeta potential of −35.4 ± 1.45 mV, with predominantly spherical and relatively smooth morphology. Encapsulation…
The properties of this gel can be modified by adding chemicals that bind to the polymer chains before UV exposure, or the UV parameters themselves can be varied to tune the gel's properties. Some of these modifications have been experimented…
An in vitro study reports that chitosan-coated titanium oxide/coumarin nanoparticles inhibit E. coli and S. aureus, eliminate about 90 percent of bacterial colony-forming units at 100 µg/mL, reduce fungal colonies, appear non-toxic in cytotoxicity assays, and showed the fastest cell movement in…
Researchers have combined flame spray pyrolysis and electrospinning to create chitosan-containing nanofiber dressings that release sustained silver ions from embedded sub-10-nm nanoparticles, showing strong activity against MRSA and Pseudomonas aeruginosa in laboratory and ex vivo human skin tests without…
A D-configured gold-nanorod and cerium-oxide composite combined near-infrared heating with antioxidant activity to improve infected-wound healing in mice.
Yuk accepted the prize a few weeks prior to successfully defending his doctoral thesis last December. These accomplishments marked the culmination of a personal journey that has its root in family tragedy. As he was completing his bachelor’s degree, Yuk…
Infected wounds are among the most stubborn problems in modern medicine. When the skin barrier is breached, bacteria colonize the exposed tissue and can sustain a pro-inflammatory microenvironment that interferes with tissue remodeling, often converting acute injuries into chronic lesions.

Scientists in Argentina grew Ganoderma sessile mycelium on alginate-hydroxyapatite hydrogels to create an anisotropic, bone-like membrane with promising mechanical stability and osteoblast compatibility for guided bone regeneration.
New research shows that the nuclear envelope protein SUN2 regulates endothelial microtubule dynamics, focal adhesions, and extracellular matrix quality to maintain blood vessel barrier function and flow responses.
Materials for medicine and biology: implants, tissue scaffolds, wound dressings, bioinks, bioadhesives and biocompatible materials.
