Micro UV Aerosol Detector

The detection of aerosols within fluid samples can be accomplished by optical methods. Such methods are useful in detecting potentially harmful aerosols such as biological aerosols that may be present after a biological agent attack or industrial accident. It is well known that biological molecules fluoresce when...

Plastic-Degrading Enzyme

Eight million metric tons of plastic waste, including polyethylene terephthalate (PET) bottles, enter the oceans each year, creating huge manmade islands of garbage. Experts estimate that by 2050, there will be as much waste plastic in the ocean by mass as there are fish. A bacterium, Ideonella sakaiensis 201-F6, can...
