Analyzing optical spectra by computer simulation

Since the total fit deviation will depend on the fit parameter values in a very nonlinear and in most cases unpredictable way, there may be ...

Optical tweezers
Optical tweezers (originally called ""single-beam gradient force trap"") are scientific instruments that use a highly focused laser beam to provide an attractive or repulsive force (typically on the order of piconewtons), depending on the refractive index mismatch to physically hold and move microscopic dielectric objects similar to tweezers. Optical tweezers have been particularly successful in studying a variety of biological systems in recent years.
