New method gives microscope a boost in resolution

Scientists at the University of Würzburg have been able to boost current super-resolution microscopy by a novel tweak. They coated the glass cover slip as part of the sample carrier with tailor-made biocompatible nanosheets ...

How skin cells protect themselves against stress

The skin is our largest organ, and, among other things, it provides protection against mechanical impacts. To ensure this protection, skin cells have to be connected to one another especially closely. Exactly how this mechanical ...

Tiny lasers light up immune cells

A team of researchers from the School of Physics at the University of St Andrews have developed tiny lasers that could revolutionise our understanding and treatment of many diseases, including cancer.

Novel quantum dots enhance cell imaging

A team of researchers from the University of Illinois at Urbana-Champaign and Mayo Clinic have engineered a new type of molecular probe that can measure and count RNA in cells and tissue without organic dyes. The probe is ...

A near-infrared fluorescent dye for long term bioimaging

A group of chemists at the Institute of Transformative Bio-Molecules (ITbM), Nagoya University, has developed a new near infrared (NIR) emitting photostable fluorescent dye PREX 710 (photo-resistant xanthene dye which can ...

How scientists analyze cell membranes

Exchange of material and information at the level of individual cells requires transport and signaling at the level of the plasma membrane enclosing the cell. Studying mechanisms at such tiny dimensions presents researchers ...

A super-resolution view of chemical reactions

Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences have demonstrated, using a super-resolution microscopic technique, how to follow chemical reactions taking place in very small volumes. ...
