nanoparticles

(Duke University Medical Center) Researchers at Duke University Medical Center have created synthetic nanoparticles that target lymph nodes and greatly boost vaccine responses, said lead author Ashley St.

(Brown University) Lab experiments find that nickel particles with diameters billionths of a meter wide can trigger a cellular pathway that promotes cancer growth.

(MedPage Today) -- Clues to olfactory function, herbs that ease asthma, nanoparticles that may destroy tumor cells, and the paradox of Tourette syndrome highlight this week's installment of Lab Notes.

(Purdue University) New research findings suggest that an experimental ultrasensitive medical imaging technique that uses a pulsed laser and tiny metallic "nanocages" might enable both the early detection and treatment of disease.The system works by shining near-infrared laser pulses through the skin to detect hollow nanocages and solid nanoparticles - made of an alloy of gold and silver - that are injected into the bloodstream.

(Biotechnology and Biological Sciences Research Council) Scientists have uncovered what happens to biomimetic nanoparticles when they enter human cells.

They found that the important proteins that make up the outer layer of these nanoparticles are degraded by an enzyme called cathepsin L.

Scientists now have to take this phenomenon into account and overcome this process to ensure the exciting field of nanomedicine can progress.

(University of Central Florida) Nanoparticles specially engineered by University of Central Florida Assistant Professor J.

Manuel Perez and his colleagues could someday target and destroy tumors, sparing patients from toxic, whole-body chemotherapies.
