By looking at the distinctive ways in which colonies of bacteria scatter laser light, US researchers have built a fast, cheap way of detecting the presence of potentially deadly microbes. The device, called a laser scatterometer, can identify bacterial colonies after just a few hours of growth.
What microscopes use laser beams?
Confocal microscopy, most frequently confocal laser scanning microscopy (CLSM) or laser confocal scanning microscopy (LCSM), is an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation.
What Tong uses?
Tongs are the tool that you use to grip something and lift it. They are usually jointed near the handle, with two grippers at the other end, so that you can one-handedly grasp objects.
