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

Prototype Separates Components of Blood for Diagnostics

The system is optimized to sort out "exosomes," biological nanoparticles released from every type of cell in the body. Thought to play a large role in cell-to-cell communication and disease transmission, they have been objects of scientific curiosity since their discovery three decades ago. The miniscule size of exosomes, however, makes

Titanium Dioxide Nanoparticles can Exacerbate Colitis

The frequency of inflammatory bowel disease like Crohn's disease and ulcerative colitis has been on the rise in many Western countries for decades. The illnesses are caused by an excessive autoimmune reaction against the intestinal flora. In addition to genetic factors, environmental factors like the Western lifestyle, especially nutrition, play

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,"

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
