In their quest to study ever smaller and smaller atom , scientist have hit on particle too modest even to be captured in a wavelength of light . What can you use to trap these particles ? Meet the electrostatic trap .
An older post on Io9 discussed optical trapsas a way to deal with mote too low or delicate to be maintain with ceremonious fixing materials . Optical manipulator trap such speck in beams of light . If the particle were to ramble one way of life , the beam of light would be diverted outwards , and kick the atom back to the heart of the beam . The post made much of how current science was entirely too involved with small thing .

It looks like scientists have broken the teeniness barrier , and are looking for equipment to enchant up . Not even light will do it , any longer . If the particle is too much smaller than the wavelength of light , the light will blow right by it instead of being amuse , and the particle will be able to break out of the trap .
Newly design to take maintenance of just such an emergency is the static trap . The trap is simple : two plates of trash separated by a liquid . belittled groove are carved into one plate .
When spyglass comes into contact with water , the glass realize a negative charge . expose the two plates of ice to urine will therefore give them a negative charge . Since both of them are negatively charged , they will repel each other .
They will also repel any negatively - charged object put between them . The object will drown around the fluid between the plates , basically ping - ponging between the side . Until it strike one of the vallecula . Since the groove mean one dental plate is far by , there will be a small area where the minus thrill lessens . Once the object slip into this area , it wo n’t be inclined to wander out , since every direction will signify an increase in negatively charged bursting charge .
The trap can keep a speck in that small area for hour , feed scientists a probability to study it . I ’m assuming it ’s too small to be studied with comically outsized magnifying glasses , but since that can be the only comfort in not being able-bodied to trap things with lasers any longer , I imagine that that ’s what the scientist will use .
