Separating the good from the bad in bacteria

There are good bacteria and there are bad bacteria—and sometimes both coexist within the same species. Take, for instance, Pseudomonas aeruginosa, a microbe common in soil and water. This bacterium has been found to colonize ...

Scientists push and pull droplets with graphene

Scientists at the U.S. Naval Research Laboratory (NRL) have moved liquid droplets using long chemical gradients formed on graphene. The change in concentration of either fluorine or oxygen formed using a simple plasma-based ...

Microfluidic breakthrough in biotechnology

Chemical flasks and inconvenient chemostats for cultivation of bacteria are likely soon to be discarded. Researchers from the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw were first to construct ...

Lab-on-a-chip technology gets a flexible upgrade

Microfluidic devices move liquids through tiny, hair-sized pathways carved into glass slides and have distinct advantages over traditional laboratories when it comes to medical diagnostics. At these reduced scales, fluid ...

An all-glass lab-on-a-chip

Lab-on-a-chip devices are microfluidic cells that incorporate pipes, reaction vessels, valves and a host of other implements typically found in laboratories. These components are typically carved into a flat plastic plate ...
