Squirtable Elastic Surgical Glue Seals Wounds in 60 Seconds

Biomedical engineers from the University of Sydney and the United States collaborated on the development of the potentially life-saving surgical glue, called MeTro. MeTro's high elasticity makes it ideal for sealing wounds in body tissues that continually expand and relax -- such as lungs, hearts and arteries -- that are otherwise

Motorized Molecules Drill Through Cells

Researchers at Rice, Durham (U.K.) and North Carolina State universities demonstrated in lab tests how rotors in single-molecule nanomachines can be activated by ultraviolet light to spin at 2 to 3 million rotations per second and open membranes in cells. The researchers used motors based on work by Nobel laureate Bernard

Smart Fabric Neutralizes Nerve Gas

The fabric consists of a cotton support modified with Cu-BTC MOF/oxidized graphitic carbon nitride composites. The latter were developed in the lab previously and tested as nerve agent detoxification media and colorimetric detectors. Combining Cu-BTC and g-C3N4-ox resulted in a nanocomposite (MOFgCNox) of heterogeneous porosity and chemistry. Upon the deposition of

PFOA Threat to Drinking Water Addressed With Novel Material

A Northwestern University-led research team now reports an inexpensive and renewable material that rapidly removes PFOA from water. The novel treatment effectively eliminates the micropollutant to below 10 parts per trillion, far below Environmental Protection Agency and all state health advisory limits. "Our material fully extracts the pollutant out of water,"

Student Creates First Synthetic Retina for The Visually Impaired

Until now, all artificial retinal research has used only rigid, hard materials. The new research, by Vanessa Restrepo-Schild, a 24 year old Dphil student and researcher at the Oxford University, Department of Chemistry, is the first to successfully use biological, synthetic tissues, developed in a laboratory environment. The study could

Nanorockets Now Available With Brakes and A Steering Wheel

Tiny machines like nanorockets are ideal candidates for drug delivery in the human body. Chemists at Radboud University now demonstrate the first complete movement regulation of a nanorocket, by providing temperature responsive brakes. An interesting feature for practical applications, since temperature sensitivity enables the rocket to stop in diseased tissues
