摘要： Provided herein are new methods and apparatus for quantitative measurement and analysis of particles, including new apparatus systems to process and detect nanoparticles in suspension. By focusing a laser beam at the center of a reservoir, nanoparticles are concentrated by optical energy, and fluorescent intensity at the focal point of the laser is measured to quantify particle concentration in the reservoir. The techniques may be applied to the analysis of suspensions of nanoparticles, including natural particles (e.g., microorganisms including whole viruses, bacteria, animal cells, and proteins) and synthetic particles (e.g., colloidal latexes, paints, pigments, and metallic or semiconductor nanoparticles) for medical and industrial applications, among others.

摘要： There remains an unmet need for methods to efficiently concentrate and isolate small particles, such as nano-sized and micron-sized particles. The methods herein provide means to fulfill this need through the combination of two independent particle-concentrating mechanisms, yielding unprecedented control, confinement, and concentration enhancement ability. The method is carried out in a reversible and spatially controllable manner. Useful applications include diagnostics and bioparticle separation, material science and research uses, among other uses.
