摘要： A bio-sensor is mounted in a container and comprised of a receptor for selectively reacting with a specific biochemical substance in a sample liquid held in the container to bind thereon the specific biochemical substance and a resonator integrated with the receptor for detecting the amount of the specific biochemical substance bound to the receptor in terms of a resonant frequency shift of the resonator. A measuring circuit is connected to the sensor for measuring the resonant frequency shift of the resonator within the container; a switching valve operates during the reaction of the receptor with the specific biochemical substance to charge a sample liquid into the container to contact the sample liquid with the receptor to thereby effect the reaction and operates during the measurement of the resonant frequency shift to replace the sample liquid by a buffer liquid in the container to immerse the sensor in the buffer liquid to thereby prevent a fluctuation of the resonant frequency shift.

摘要： A viscosity measuring system comprises a cell containing gelable liquid and a piezoelectric resonator mounted in the cell. The piezoelectric resonator has a prescribed characteristic, such as electrical resistance or resonant frequency, which varies in accordance with the gelating of the liquid. Solid particles suspended in the liquid are deposited on the piezoelectric resonator during gelating of the liquid to amplify the prescribed resonator characteristic. A measuring circuit measures the variation of the resonator characteristic to thereby determine the gelation time of the liquid.

摘要： A scanning near-field optic/atomic-force microscope comprises a holder for holding a sample immersed in a liquid, and a plate disposed over the holder for covering a surface of the liquid and for transmitting therethrough a laser light. A probe has an optical propagation body terminating in a distal end, and a light reflecting element disposed thereon, and the probe is immersed in the liquid. A light source emits a light which is introduced into the optical propagation body of the probe, which guides the light through the probe and out the distal end thereof to irradiate the sample. A detecting device detects information from the light irradiated on the sample and converts the information to an electric signal. A laser source irradiates the light reflecting element of the probe with a laser light for detecting a bending amount of the probe resulting from an interaction between the sample and the probe. An angle adjusting mechanism adjusts an optical axis of the laser light transmitted through the plate. A photoelectric conversion device receives the laser light reflected from the light reflecting element and converts the reflected light into an electric signal. A moving mechanism moves the sample relative to the probe, and a distance control device controls a distance between the surface of the sample and the distal end of the probe.
