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.

Nanosilver used in medications as early as 1889

Nanosilver is not a new discovery by nanotechnologists - it has been used in various products for over a hundred years, as is shown by a new Empa study. The antimicrobial effects of minute silver particles, which were then known as "colloidal silver", were known from the earliest days of its use.

Silver studded bacteria could help treat common cold and flu

Finally scientists may have found a potential cure for common cold. They have found “silver bullets” in yogurt that could destroy viruses and provide a cure for the flu and common cold.

An overview of ESA-s Annual Meeting

Whether it is a single rock being overturned or an entire mountaintop being removed, humans play a continuous role in environmental processes, and vice versa. Ecological scientists will discuss findings on human-ecosystem interactions-from the effects of nanomaterials on plant growth to the diversity of insect species on green roofs, and even communities of airborne microbes in hospital buildings-at the Ecological Society of America's 95th Annual Meeting in Pittsburgh from August 1-6, 2010. Here is just some of the research on humans and the environment to be presented:

Silver nanoparticles effective at killing all kinds of bacteria

Writing in the International Journal of Nanoparticles, Rani Pattabi and colleagues at Mangalore University, explain how blasting silver nitrate solution with an electron beam can generate nanoparticles that are more effective at killing all kinds of bacteria, including gram-negative species that are not harmed by conventional antibacterial agents.

Ensuring medication compliance in clinical trials: Pill capsules with microchips to signal ingestion

Seeking a way to confirm that patients have taken their medication, University of Florida engineering researchers have added a tiny microchip and digestible antenna to a standard pill capsule. The prototype is intended to pave the way for mass-produced pills that, when ingested, automatically alert doctors, loved ones or scientists working with patients in clinical drug trials.

USGS researchers examine PAHs and PCBs sources in urban environment

Toxic dust: Toxins in coal-tar-based sealcoats in parking lots may be the culprit in contaminated house dust, according to a USGS study. PAHs - or polycyclic aromatic hydrocarbons - are large molecules found in oil, coal and tar deposits, and can have toxic effects.

Nanoparticles from antibacterial textiles could harm fish and other wildlife

Scientists in Switzerland are reporting results of one of the first studies on the release of silver nanoparticles from laundering those anti-odor, anti-bacterial socks now on the market. Their findings, scheduled for the Nov. 1 issue of ACS' journal Environmental Science & Technology, may suggest ways that manufacturers and consumers can minimize the release of these particles to the environment, where they could harm fish and other wildlife.

New technique enables the detection of biomolecules' dynamic reactions in a single living cell

By taking advantage of the signature frequency by which organic and inorganic molecules absorb light, the team of researchers, led by Luke Lee, professor of bioengineering and director of UC Berkeley's Biomolecular Nanotechnology Center, can determine in real time whether specific enzymes are activated or particular genes are expressed, all with unprecedented resolution within a single living cell.

Nanoscale dots target and track apoptosis

Apoptosis, or programmed cell death, is a hallmark effect triggered by effective anticancer drugs. Now, researchers in Korea have developed a biocompatible, fluorescent nanoparticle that could provide an early sign that apoptosis is occurring as a result of anticancer therapy.
