Biological particles are ideal for arrangement of nanoparticles

Nanocomposite

It has always been the Holy Grail of materials science to describe and control the material’s structure-function relationship. Nanoparticles are an attractive class of components to be used in functional materials because they exhibit size-dependent properties, such as superparamagnetism and plasmonic absorption of light. Furthermore, controlling the arrangement of nanoparticles …

Nano-sized carrier systems find medical application

Comparison of nanomaterials_sizes

Nano-sized carrier systems find medical application to improve pharmacologic properties of bioactive agents. For many therapeutic approaches, it is important that the carrier system can stably incorporate the cargo during circulation without inducing aggregation, while cargo should ideally only be released after successful cellular uptake. These requirements have thus far …

A nanomedical tool could make therapies for variety of diseases

MRNA-interaction

A new nanomedical tool using nanoparticles that deliver transient gene changes to targeted cells could make therapies for a variety of diseases — including cancer, diabetes and HIV — faster and cheaper to develop, and more customizable. The tool, developed by researchers at Fred Hutchinson Cancer Research Center and tested …

Researcher uses gold nanostars to heat up and destroy tumors. 

Gold Nanostar

By combining an FDA-approved cancer immunotherapy with an emerging tumor-roasting nanotechnology, Duke University researchers improved the efficacy of both therapies in a proof-of-concept study using mice.  The potent combination also attacked satellite tumors and distant cancerous cells, completely curing two mice and effectively vaccinating one against the disease. The new …
