Scientists discover a new method to produce gold nanoparticles

Gold nanoparticles, tiny pieces of gold so small that they can't be seen by the naked eye, are used in electronics, healthcare products and as pharmaceuticals to fight cancer. Despite their positive uses, the process to make the nanoparticles requires dangerous and extremely toxic chemicals. While the nanotechnology industry is expected to produce large quantities of nanoparticles in the near future, researchers have been worried about the environmental impact of the global nanotechnological revolution.

Hybrid scanner helps to enhance visibility of skin cancer cells

Scientists are reporting development of a substance to enhance the visibility of skin cancer cells during scans with an advanced medical imaging system that combines ultrasound and light. The hybrid scanner could enable doctors to detect melanoma, the most serious form of skin cancer, in its earliest and most curable stages, the report in the monthly journal ACS Nano indicates.

Breath test to detect cancer: Study

According to researchers cancer may soon be detectable using a breath test. They are now developing sensors that can detect chemical markers of lung, breast, bowel and prostate cancer in a person's breath. The new portable device has been purported as an “electronic nose” that can detect early cancers. As a cancer grows, the surface of the cells emits chemicals. The research found that sensors – involving gold nanoparticles – could be used to detect these chemicals in the breath.

Scientists develop laser activated carbon nanoparticles for drug, gene delivery

Using chemical "nanoblasts" that punch tiny holes in the protective membranes of cells, researchers have demonstrated a new technique for getting therapeutic small molecules, proteins and DNA directly into living cells.Carbon nanoparticles activated by bursts of laser light trigger the tiny blasts, which open holes in cell membranes just long enough to admit therapeutic agents contained in the surrounding fluid. By adjusting laser exposure, the researchers administered a small-molecule marker compound to 90 percent of targeted cells - while keeping more than 90 percent of the cells alive.

High sensitivity of Zetasizer Nano proves essential for protein aggregation studies

Dr Martin Muschol, Assistant Professor at the University of South Florida’s (USF) Department of Physics and his team are carrying out important research to gain a better understanding of protein aggregation phenomena, including protein crystallization and amyloid fibril growth. Using the Zetasizer Nano ZS, from Malvern Panalytical (Malvern Panalytical, UK), the USF researchers have been able to perform temperature controlled static and dynamic light scattering (DLS) measurements of protein hydration, protein interactions and aggregation kinetics in vitro.
