A low-cost prototype device described in a recent paper* can run up to eight separations simultaneously in a space about the size of a quarter, highlighting…
Precise diagnosis is based on multiple end-points involving several tests with antibodies or DNA probes for particular biomolecules in a tumor or a virus. Antibodies and DNA are usually labeled with different fluorescent dyes, generally requiring multiple modes of excitation and detection that can render the measurement slow and laborious. Advances in nanotechnology have led to the emergence of new fluorescent materials, semiconductor nanoparticles (NPs) called “quantum dots”, which can be excited by a single light source (wavelength) but that according to their size and composition emit in discrete and separated spectral bands. …
Now, a team of scientists from the Whitehead Institute and the Dana-Farber Cancer Institute have identified a key set of genes that lie at the core of…
RNA plays an important and direct role in the synthesis of proteins, the building blocks of our bodies. However, scientists have known for some time that not…
