Active microvalves and passive microvalves in microfluidic chips. (A) Typical structure of active microvalve: sliding arm. PDMS structures contain a guiding channel and a fluidic channel and were ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2022.210121 discusses label-free trace detection of bio-molecules by liquid-interface assisted surface-enhanced Raman scattering using ...

With the recent advances in genomics, combinatorial chemistry, and automation, drug discovery scientists working in pharmaceutical, biotechnology, and academic environments are faced with the ...

Researchers have developed a new method for detecting foodborne pathogens that is faster, cheaper, and more effective than existing methods. Their microfluidic chip uses light to detect multiple types ...

The blood-brain barrier protects the central nervous system by tightly regulating what crosses between the two compartments. Neurons are vulnerable if the barrier suffers damage or weakens with age, ...

Chemists have created a device -- using little more than paper and sticky tape -- that can precisely separate liquids for further medical or environmental analysis. The scientists write in a ...

A complete blood count can help ascertain the health of a patient and typically includes an estimate of the hemoglobin concentration, which can indicate several conditions, including anemia, ...
