Inserting, removing or swapping individual atoms from the core of a molecule is a long-standing challenge in chemistry. This ...

Invented 30 years ago, the atomic force microscope has been a major driver of nanotechnology, ranging from atomic-scale imaging to its latest applications in manipulating individual molecules, ...

Physicists at the University of Regensburg have found a way to manipulate the quantum state of individual electrons using a microscope with atomic resolution. The results of the study have now been ...

Analyzing structures and physicochemical properties of biomolecules is a major field of research in biotechnology. The four major types of biological macromolecules namely, carbohydrate, proteins, ...

Our bodies comprise different tissues and organs, which are composed of many cells that must adhere to form functional higher order structures. This adherence is facilitated by specialized proteins ...

Atomic force microscopy (AFM) and infrared (IR) spectroscopy have emerged as complementary techniques that enable the precise characterisation of materials at the nanoscale. AFM provides ...

Fast-scanning atomic force microscopy imaging of the molecule at two different time points shows positional shifts along the polymer chain on the left. On the right, the molecular structure of PEG ...

Atomic force microscopy (AFM) is a method of topographical measurement, wherein a fine probe is raster scanned over a material, and the minute variation in probe height is interpreted by laser ...

Christoph Gerber, who co-invented the atomic force microscope, tells Matthew Chalmers how the AFM came about 30 years ago and why it continues to shape research at the nanoscale Nano-vision Christoph ...

In what's being hailed as an important first for chemistry, an international team of scientists has developed a new technology that can selectively rearrange atomic bonds within a single molecule. The ...
