Abstract
This invention provides new methods and apparatus for rapidly analyzing single bioparticles to assess their material condition and health status. The methods are enabled by a resonant cavity to measure optical properties related to the bioparticle size and refractive index. Refractive index measurements are useful for determining material properties and biomolecular composition of the bioparticle. These properties and composition are dependent on the health state of the bioparticle. Thus, measured optical properties can be used to differentiate normal (healthy) and abnormal (diseased) states of bioparticles derived from cells or tissues. The methods are illustrated with data obtained from a resonator with a gain medium. The invention also provides new methods for multiple measurements in a single device, analyzing and manipulating bioparticles that are much smaller than the wavelength of light, and provides a microfluidic transport chip to enable rapid single bioparticle analysis of large populations of bioparticles.
