Silver Nanoparticles News and Research

RSS

Silver nanoparticles are made wholly or partly from metallic silver, exist in various shapes, and range 1–100 nm in diameter. Their small size and ability to induce cell death through multiple mechanisms makes them fantastic pharmacological candidates.

New device detects signs of sudden cardiac death

Scientists of Tomsk Polytechnic University have developed a nanosensor-based hardware and software complex for measurement of cardiac micropotential energies without filtering and averaging-out cardiac cycles in real time.

New bacteria-killing light-activated coating

A new antimicrobial coating that can be activated by light has been reported by researchers in the journal Nature Communications, in March 2020. The coating can be used to prevent transmission from computer and phone screens and keyboards, the inside of catheters, and breathing tubes. All these are significant routes of healthcare-associated infections (HCAIs).

Bioinspired adhesive dressings could accelerate wound healing

Cuts, scrapes, blisters, burns, splinters, and punctures - there are a number of ways our skin can be broken. Most treatments for skin wounds involve simply placing a barrier over them (usually an adhesive gauze bandage) to keep it moist, limit pain, and reduce exposure to infectious microbes, but do not actively assist in the healing process.
