    摘要: A technique for making precise spectrophotometric measurements illuminates a sample with two or more modulated light sources at two or more, typically closely spaced, wavelengths. Light from the sources is combined, homogenized, and directed to the sample, and the light from the sample is collected and detected by a photodetector. The optical output powers of two sources are modulated with the same periodicity and with a reversed amplitude. Variations in the concentrations of species in the sample affect the modulation amplitude representing the sum of the optical powers from two sources in such a way as to produce an output signal. That output signal, based on an electrical component varying with a periodicity at the fundamental frequency, provides a measure of the difference in the transmissions (or other optical properties) of the sample at the two wavelengths. Feedback methods, such as null-point detection, provide stable, sensitive measurements. Wavelength-division multiplexing--required for simultaneous measurements at many wavelengths--is achieved by modulating different pairs of sources at different frequencies.

    摘要: A sample probe includes a tip including a distal end for penetrating a cellular membrane, an opening located at or proximal to the distal end, and tip microchannels extending through the tip and communicating with the opening; and a body adjoining the tip and including body microchannels, wherein at least one of the body microchannels communicates with at least one of the tip microchannels. A method for sampling intracellular material includes inserting a probe tip through a cellular membrane; aspirating intracellular material from the cell, through an opening of the tip, and into a first microchannel of the tip; flowing isolator fluid from a second microchannel of the tip into the first microchannel to form a plug of intracellular material; and aspirating the plug and the isolator fluid through the first microchannel.

One embodiment of the present invention is an imaging apparatus comprising a holder for a surface, a light source adapted to illuminate the surface, a diffractive element between the holder and the light source and an imaging detector adapted to receive light from the surface. In a method for imaging a surface comprising a plurality of discrete features, light is selectively diffracted on to one or more predetermined features of the surface at a predetermined point in time. This step is repeated until substantially all of the features on the surface are illuminated. Light is detected from the surface to thereby image the surface.
