Abstract: PROBLEM TO BE SOLVED: To realize a screening method capable of analyzing multiple specimens in a short time by detecting an active compound based on the change of a signal which can be observed by using a device for a scanning atomic force microscopic inspection. SOLUTION: A receptor 5 is fixed on a surface 4 of a support. The change of connection of an active compound 3 to the receptor 5 is measured by using a signal S. The active compound 3 is similarly fixed on a chip 1 of a scanning atomic force microscope by means of a spacer 2 in convenient. The active compound 3 is fixed on the surface 4 of the support and the receptor 5 is on the chip 1 of the microscope. Firstly, the chip 1 is coated with an evaporation layer of chromium as an adhesion accelerator having a thickness of, for example, 5nm, then it is coated with a gold having a thickness of 50nm. The chip 1 coated with gold is similarly coated with mercapto carboxylic acid and a spacer 2 is suspended on the chip 1. When estimation is executed by simultaneously using a plurality of probes, a piezoelectric cantilever is utilized.

Abstract: The invention relates to a highly sensitive surface-wave gas sensor in which the frequency of an oscillatory circuit containing a surface-wave delay line is altered as a function of the type of gas and gas concentration as a result of the interaction of a surface-wave field with a solid-state film suitable for adsorbing the gas to be determined. The delay line provided for the adsorption of the gas is completely coated with the solid-state film and the dimensioning of the delay lines is such that the length of the surface-wave transducer is greater than that of the delay line.

Abstract: The novel compounds of the general formula I having nonlinear optical properties in which the variables have the following meaning: X is a straight-chain or branched alkanediyl radical having 1 to 20 C atoms or X is a straight-chain or branched alkanediyl radical having 2 to 20 C atoms, the carbon chain of which is interrupted by -O-, -S- and/or -NR-; R is a hydrogen atom, a straight-chain or branched alkyl radical having 1 to 6 C atoms or a cycloalkyl radical, Y is a non-centrosymmetrical radical containing an easily polarisable conjugated pi -electron system and at least one terminal electron acceptor group; are outstandingly suitable as nonlinear optical materials for nonlinear optical arrangements and for the preparation of polymers having nonlinear optical properties. In particular, they are used for the preparation of organopolysiloxanes having nonlinear optical properties and which contain side groups of the general formula Ia in which the variables have the abovementioned meaning. These novel organopolysiloxanes having nonlinear optical properties are in turn outstandingly suitable for the preparation of Langmuir-Blodgett films.
