Tweezers come in a variety of tip shapes and sizes. [4] Blunt tip tweezers have a rounded end which can be used when a pointed object may get entangled, when manipulating cotton swabs, for example. Flat tip tweezers, pictured at right, have an angled tip which may be used for removing splinters. Some tweezers have a long needle-like tip which ...
By patterning the surface with gold microscopic islands it is possible to have selective and parallel trapping in these islands. The forces of the latter optical tweezers lie in the femtonewton range. [72] The evanescent field can also be used to trap cold atoms and molecules near the surface of an optical waveguide or optical nanofiber. [73] [74]
The tweezer manufacturers simply added an ‘S’ to the style number to signify that the tweezer was made of Stainless Steel. In the 1950’s, the birth of the electronic industry spurred the need for a material that had less magnetism. Precision tweezers began popping up made of AISI 303/304 and AISI 316 Stainless Steel.

Antonie van Leeuwenhoek (1632–1723). The field of microscopy (optical microscopy) dates back to at least the 17th-century.Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century [2] but more advanced compound microscopes first appeared in Europe around 1620 [3] [4] The ...
The first patient in the U.S. was hospitalized with "severe" bird flu. Here's what you should know about symptoms, according to an infectious disease expert.
The name of photonic force microscope was first used in 1997 by Ernst-Ludwig Florin, Arnd Pralle, J. Heinrich Hoerber and Ernst H.K. Stelzer during their stays at EMBL, when they developed 3D position detection and began using the Brownian motion as scanner.
