摘要： The present invention relates to systems and methods for measuring one or more physical characteristics of material such as tissue using optical radiation. The system can use light that is scattered by a tissue layer to determine, for example, the size of nuclei in the tissue layer to aid in the characterization of the tissue. These methods can include the use of fiber optic devices to deliver and collect light from a tissue region of interest to diagnose, for example, whether the tissue is normal or precancerous.

摘要： Removal of body tissue with a long pulsed lasers is achieved such that sufficient energy to remove tissue is transmitted to the desired body without damaging an optical fiber transmitting the laser radiation. Pairs of pulses having the same or different wavelengths are coupled to more effectively remove tissue from the surgical site.

摘要： The present invention relates to the use of polarized light to measure properties of tissue. More particularly, polarized light can be used to detect dysplasia in tissue as the polarization of back-scattered light from such tissues is preserved while the contribution of diffusely scattered light from underlying tissues can be removed. A fiber optic system for delivery and collection of light can be used to measure tissues within the human body.

摘要： Surface-enhanced spectroscopy, such as surface-enhanced Raman spectroscopy employs aggregates that are of a size that allows easy handling. The aggregates are generally at least about 500 nm in dimension. The aggregates can be made of metal particles of size less than 100 nm, allowing enhanced spectroscopic techniques that operate at high sensitivity. This allows the use of larger, easily-handleable aggregates. Signals are determined that are caused by single analytes adsorbed to single aggregates, or single analytes adsorbed on a surface. The single analytes can be DNA or RNA fragments comprising at least one base.
