Artificial retina using synthetic and biological materials

A synthetic, soft tissue retina made of hydrogels and biological cell membrane proteins was developed by an Oxford University student Vanessa Restrepo-Schild. Research involved combining biological and synthetic tissues in a laboratory. Designed like a camera, the aqueous droplets containing bacteriorhodopsin (bR), a light-driven proton pump act as pixels, detecting and reacting to light to … Continue reading Artificial retina using synthetic and biological materials

Glassy carbon electrodes advances brain-computer interface technology

The Center for Sensorimotor Neural Engineering-a collaboration of San Diego State University with the University of Washington and the Massachusetts Institute of Technology is working on an implantable brain chip that can record neural electrical signals and transmit them to receivers in the limb. Results of the research study utilizing above technology are published in … Continue reading Glassy carbon electrodes advances brain-computer interface technology

Development of thin-film biomaterials using nanofibres to be used as scaffolding for bone regeneration

In future, it may be possible to use nanofibres to improve the attachment of bone implants, or the fibres may be used directly to scaffold bone regeneration. This would aid the healing of fractures and may enable the care of osteoporosis. This is detailed in a new dissertation.Hydroxyapatite nanofibre film produced at the University of … Continue reading Development of thin-film biomaterials using nanofibres to be used as scaffolding for bone regeneration

Painless skin patch created with flexible base and stainless steel microneedles

It’s only a matter of time before drugs are administered via patches with painless microneedles instead of unpleasant injections. But designers need to balance the need for flexible, comfortable to wear material with effective microneedle penetration of the skin. Researchers from KTH Royal Institute of Technology in Stockholm say they may have cracked the problem.A … Continue reading Painless skin patch created with flexible base and stainless steel microneedles

Carbon nanotube based electrical immunosensor to rapidly detect troponin I during a heart attack

Heart disease is the leading cause of death for both men and women. Therefore, a fast and reliable diagnosis of heart attack is urgently needed. A study, led by Prof. Jaesung Jang (School of Mechanical and Nuclear Engineering) has developed an electrical immunosensor to detect the acute myocardial infarction, also known as a heart attack … Continue reading Carbon nanotube based electrical immunosensor to rapidly detect troponin I during a heart attack

Universal shear-thinning biomaterial for endovascular embolization.

Researchers at Mayo Clinic, Harvard Medical School and the Massachusetts Institute of Technology are developing a biomaterial that has potential to protect patients at high risk for bleeding in surgery. The article"An Injectable Shear-Thinning Biomaterial for Endovascular Embolization," in the journal Science Translational Medicine reports on a universal shear-thinning biomaterial that may provide an alternative … Continue reading Universal shear-thinning biomaterial for endovascular embolization.
