Nanoplasmonic Sensors Based on Chirped Crossed Surface Relief Gratings
This work presents a new type of nano-plasmonic sensor based on crossed surface relief gratings (CSRGs) with gradually varying pitch generated on top an azobenzene thin films using a 532 nm laser and a modified Lloyd mirror ... -
Neutrophil NETosis, viability, and gene or protein expression in response to surface chemistry using isodecyl acrylate copolymer coatings
Undesirable host responses to implants commonly lead to impaired device function. Biomaterial-based strategies focused on neutrophil behavior to improve host responses to implants have not been significantly researched. ... -
A New Approach to Make Starch Graft Copolymers via Nitroxide-Mediated Polymerization
Starch is one of the most abundant polysaccharides worldwide next to cellulose. Starch bio-polymers are sustainable, biodegradable, and abundant, but are often chemically modified to improve the physical or chemical ... -
