Abstract: An electrochemical sensor allows even extremely small quantities or concentrations of a target chemical substance to be detected or quantified with a high precision in a particularly reliable manner. The novel sensor has a detector zone formed by nanoparticles which are embedded in a matrix and have a higher electric conductivity than the matrix material. The electric conductivity of the zone is determined by electron tunneling, ionization or hopping processes among the nanoparticles and by the electrochemical interaction thereof with a target substance to be detected.

Abstract: A miniaturized spring element is intended to be particularly suitable for use as a beam probe or cantilever for detecting atomic or molecular forces, in particular in an atomic force microscope, and, to this end, is intended to make it possible to detect its deflection in a particularly reliable manner and with high resolution. For this purpose, the spring element contains a basic body which is formed from a matrix containing embedded nanoparticles or defects. The spring element is produced using the principle of local deposition with focused energetic particles or electromagnetic waves or by pyrolytically induced deposition.

Abstract: The matter for which the refractive index is to be determined, is made available in the form of a theoretically determinable scattering or diffraction pattern. Two or more orders of diffraction may then be defined to form at least one intensity ratio. At least one intensity distribution may be formed by irradiating the scattering pattern using one light beam of a defined shape. Subsequently thereto, the intensity ratio may be formed based on the orders of diffraction of the intensity distribution. In addition, at least one portion of a characteristic curve may be determined, which represents the dependency of the intensity ratio on the refractive index, and, with whose assistance, the corresponding refractive index can be assigned to the intensity ratio formed.

Abstract: Inordinate localised systems are used at room temperature in a novel device in the form of an electron spectrometer for utilising single-electron electronic applications. Said electron spectrometer device consists of a nanocrystalline metal or a nanocrystalline semiconductor material used as conductor strip connection in the form of an inlet or an outlet for single-electron electronic components and circuits consisting of lithographically produced quantum dots. The resulting single-electron electronic device consisting of quantum dots is supplied with energetically very sharply defined electrons. Said device can thus be operated at room temperature, undisturbed by phonons.
