Researchers developed a new synthetic adhesive that mimics gecko toe hairs, allowing for directional adhesion on smooth surfaces. The adhesive is made from hard plastic microfibers that become stronger with use and can detach without residue.
Researchers found that the biodegradable film reduced severe scarring by 30% compared to controls. The film was effective in reducing adhesions in patients with high-risk procedures, such as cardiopulmonary bypass and delayed incisions.
Researchers discovered Ginsenoside Rb1 prevents hepatic microcirculatory disturbance and liver injury in mice subjected to intestine ischemia and reperfusion. The compound is a major effective ingredient of Panax notoginseng, a traditional Chinese herb medicine.
Scientists at Georgia Tech discovered that certain cells can retain information about previous encounters through receptor-ligand interactions. This finding suggests that sequential measurements may not be independent and could impact research conclusions.
Scientists create a surface pair that sticks together in response to an environmental stimulus, allowing for reversible detachment. This discovery could lead to innovative applications in microfluidic systems, actuators, and pharmacological agents.
Researchers have developed a synthetic adhesive, called 'geckel,' that exhibits strong yet reversible adhesion in both air and water. The material combines the adhesive properties of geckos with those of mussels, showing improved wet adhesion 15-fold over uncoated pillar arrays.
Physicist Lawrence Schein's research uses nano-coating technology to reduce toner adhesion, enabling simplified and cheaper color laser printers. Current models are more expensive and up to three times larger than black-and-white models.
Researchers use computer simulations to study the effect of adhesive patch size and density on cell adhesion. They found that protrusion height is the most critical factor, with small increases leading to faster adhesion rates.
