Attaching transferrin to nanoparticle surface can kill cancer cells

A normally benign protein found in the human body appears to be able - when paired with nanoparticles - to zero in on and kill certain cancer cells, without having to also load those particles with chemotherapy drugs.The finding could lead to a new strategy for targeted cancer therapies, according to the University of North Carolina at Chapel Hill scientists who made the discovery.

Scientists develop nanoprobe to detect blood vessel growth in tumors

Formation of new blood vessels, also known as angiogenesis, is crucial for sustained tumor growth and cancer metastasis. Recently, clinically available therapies to suppress the growth of these vessels have been available to improve patient survival in some cancer types. Accurate detection and quantification of blood vessel growth using nonsurgical methods would greatly complement current therapies and allow physicians to quickly assess treatment regimens and adjust them as necessary. In the work published in the August issue of Experimental Biology and Medicine, Kessinger and coworkers have incorporated nanotechnology, material science, and the clinical imaging modality MRI, to create a nanosized probe capable of noninvasively visualizing and quantifying the blood vessel growth in tumors in a preclinical model.

Scientists discover world's first mass producible, low-cost organoclays for plastics

Scientists are reporting an in-depth validation of the discovery of the world's first mass producible, low-cost, organoclays for plastics. The powdered material, made from natural clay, would be a safer, more environmentally friendly replacement for the compound widely used to make plastics nanocomposites. A report on the research appears in ACS' Macromolecules, a bi-weekly journal.

Ivy nanoparticles protect skin from UV radiation better than metal-based sunblocks: Study

When Mingjun Zhang was watching his son play in the yard, he was hit with a burning question: "What makes the ivy in his backyard cling to the fence so tightly?" That simple question has led to a pioneering discovery that the tiny particles secreted from ivy rootlets can be used in many breakthrough applications in items such as military technologies, medical adhesives and drug delivery, and, most recently, sun-block.

Scientists report potential toxicity of nanoparticles in consumer products

Scientists are reporting that particle size affects the toxicity of zinc oxide, a material widely used in sunscreens. Particles smaller than 100 nanometers are slightly more toxic to colon cells than conventional zinc oxide. Solid zinc oxide was more toxic than equivalent amounts of soluble zinc, and direct particle to cell contact was required to cause cell death.
