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

Nanocapsules Enable Cell-Inspired Metabolic Reactions

Metabolic processes inside living organisms involve a large variety of bio-molecules. These molecules are produced by specific enzymatic reactions. One example of such a bio-molecule is glucose-6-phosphate, a metabolite that is involved in important metabolic processes. It is central in the degradation of carbohydrates and can also be converted further

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

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

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
