Scientists have developed a revolutionary new technology that can image and weigh single molecules and instantly identify a single virus or bacteria particle. A microscopic tool, more than 1000 times ...

Common in nature and found in DNA and amino acids, chiral molecules are asymmetric with a structure that’s different from its mirror image. Chiral amino acids are “left-handed” and cannot be swapped ...

WEST LAFAYETTE, Ind. – Lasers are used to carry out functions ranging from reading a bar code label at the grocery store to shooting down enemy missiles in space. Now, chemists at Purdue University ...

Water is a familiar substance that is present virtually everywhere. The properties of the first few layers of water molecules in contact with the surface of materials (called 'surface water') are ...

Organic chemistry is packed with rules about structure and reactivity, especially when it comes to making and breaking chemical bonds. The rules governing how these bonds, which hold atoms together in ...

In recent years, the results of scientific research have indicated that the substances that form natural fibers, and regenerated man-made fibers, are chemically composed of long molecules, which are ...

Helping to make creation of nano-sized structures more user-friendly, scientists have designed single-stranded DNA and RNA (ssDNA and ssRNA) that can fold into desired shapes on command, and at an ...

DeepMind has given 3-D structure to 350,000 proteins, including every one made by humans, promising a boon for medicine and drug design. By Cade Metz For some years now John McGeehan, a biologist and ...

A new material that sorts hydrocarbon molecules by shape could lower the cost of gasoline and also make the fuel safer by reducing the need for certain additives that have been linked to cancer, ...

Lasers are used to carry out functions ranging from reading a bar code label at the grocery store to shooting down enemy missiles in space. Now, chemists at Purdue University are using lasers to coax ...
