Silicones are commonly used in the field of medicine to lubricate syringes, encapsulate medical devices, and develop surgical implants. Although the material is generally viewed as relatively inert to cells, they can trigger ...
In a new study published on Scientific Reports, Mohammad-Hossein Beigi and a research team in the departments of Engineering and Applied Science and Cellular Biotechnology in Canada and Iran described a new method to form ...
Researchers have developed the first fully functional biofuel cell whose biocatalysts (enzymes that play a critical role in power generation) directly self-assemble onto the electrodes. In about 5 minutes, enzyme-nanoparticle ...
A team of researchers at Université Côte d'Azur and Centre Scientifique de Monaco has recently carried out a study aimed at better understanding the near-surface swimming patterns of bacteria. Their paper, published in ...
(PhysOrg.com) -- While the most common device for converting light into electricity may be photovoltaic (PV) solar cells, a variety of other devices can perform the same light-to-electricity conversion, such as solar-thermal ...
A team of bio-scientists affiliated with a host of institutions across the U.S. has developed a gene editing technique to produce newborn pigs immune to porcine reproductive and respiratory syndrome, also known as blue-ear ...
Researchers have used 3D cell culture models in the past decade to translate molecular targets during drug discovery processes to thereby transition from an existing predominantly 2D culture environment. In a new report now ...
In a first, scientists have captured on video all the steps a virus follows as it enters and infects a living cell in real time and in three dimensions.

In biochemistry, a receptor is a protein molecule, embedded in either the plasma membrane or cytoplasm of a cell, to which a mobile signaling (or "signal") molecule may attach. A molecule which binds to a receptor is called a "ligand," and may be a peptide (such as a neurotransmitter), a hormone, a pharmaceutical drug, or a toxin, and when such binding occurs, the receptor undergoes a conformational change which ordinarily initiates a cellular response. However, some ligands merely block receptors without inducing any response (e.g. antagonists). Ligand-induced changes in receptors result in physiological changes which constitute the biological activity of the ligands.
