Scientists at Georgia Tech have developed a nanolithographic technique that can produce high-resolution patterns of at least three different chemicals on a single chip at writing speeds of up to one millimeter per second. The chemical nanopatterns can be tailor-designed with any desired shape and have been shown to be sufficiently stable so that they [...]

By producing some of the highest resolution images of peptides attaching to mineral surfaces, scientists have a deeper understanding of how biomolecules manipulate the growth of crystals. This research may lead to a new treatment for kidney stones using biomolecules.

Researchers in the United States and Spain have discovered that a tool widely used in nanoscale imaging works differently in watery environments, a step toward better using the instrument to study biological molecules and structures.

It’s well known that the protein calmodulin specifically targets and steers the activities of hundreds of other proteins – mostly kinases – in our cells, thus playing a role in physiologically important processes ranging from gene transcription to nerve growth and muscle contraction But just how it distinguishes between target proteins is not well understood.
