Scar-Detecting Nanoparticles

by
keloid_hypertrophic_scars

Scars are the body’s response to skin injury. Sometimes too much of the protein collagen is produced at the site of the injury, resulting in excessively large thick scars that can be disfiguring, uncomfortable, and compromise function by restricting mobility. These can either be hypertrophic scars, which are thickened but limited to the injured area, … Read more

Spasers: Nanoparticles that Make Deadly Bubbles to Kill Cancer Cells

by
Spaser

Spasers are energy-absorbing particles that release light. Spaser stands for “surface plasmon amplification by stimulated emission of radiation.” These tiny particles are a type of plasmonic nanoparticle. Lasers activate spasers, which can be targeted to cancer cells. Once internalized by cancer cells, spasers can selectively kill them. Galanzha and colleagues generated and tested spasers of … Read more
