A wearable device for regrowing hair

Wed, 09/12/2018 - 19:18
Although some people embrace the saying 'bald is beautiful,' for others, alopecia, or excessive hair loss, can cause stress and anxiety. Some studies have shown that stimulating the skin with lasers can help regrow hair, but the equipment is often large, consumes lots of energy and is difficult to use in daily life. Now, researchers have developed a flexible, wearable photostimulator that speeds up hair growth in mice.

New nanoparticles wait to release drugs, target infection

Tue, 09/11/2018 - 21:21
Current research shows stimuli-responsive nanoparticles can specifically target infections to simultaneously prevent the spread of bacteria and reduce the inflammation it causes. These microscopic particles are loaded with antibiotic and anti-inflammatory agents which are released when the particles encounter infection in the body. Researchers in the lab of Pharmaceutical Sciences Assistant Professor Zhenjia Wang are looking for a new way to fight sepsis, a systemic inflammatory response that can cause organ failure.

Engineers protect artifacts by graphene gilding

Tue, 09/11/2018 - 21:20
Gilding is the process of coating intricate artifacts with precious metals. Ancient Egyptians and Chinese coated their sculptures with thin metal films using gilding. Scientists inspired by this ancient process, have added a single layer of carbon atoms, known as graphene, on top of metal leaves -- doubling the protective quality of gilding against wear and tear.

Carbon nanodots do an ultrafine job with in vitro lung tissue

Tue, 09/11/2018 - 19:45
Epidemiological studies have established a strong correlation between inhaling ultrafine particles from incomplete combustion and respiratory and cardiovascular diseases. Still, relatively little is known about the mechanisms behind how air particulates affect human health. New work seeks to provide the first model of how ultrafine carbon-based particles interact with the lung tissues. Researchers created a 3D lung cell model system to investigate how carbon-based combustion byproducts behave as they interact with human epithelial tissue.
