Abstract: This invention is related to a reproducible identification method based on surface-enhanced Raman scattering (SERS), in which bacterial samples are used in identification of bacteria by mixing with the concentrated silver and gold nanoparticles.

Abstract: Power management methods, systems and circuitry are provided for efficiently energizing implanted stimulators. Efficiency is achieved by automatically adjusting the power-supply voltage of the stimulator channel so that the magnitude of the voltage of the current-sink or current-source providing the stimulation current is regulated within a narrow band just above the minimum acceptable level. Adjustment is done once in every cycle of the external high-frequency power source in order to achieve regulation with a very fine time resolution throughout each stimulation period. The power supply voltage is generated and adjusted by rectifying the high-frequency voltage of the secondary coil of a transcutaneous magnetic link by closing and opening a solid-state switch at appropriate times during positive half cycles for a current-sink, and during negative half-cycles for a current-source.

Abstract: The present invention relates to a granulated lyophilized effervescent biopesticide granule and production method (10) thereof. By means of the inventive method (10), an economical biopesticide with high applicability is obtained, which does not have harmful effect on environment and human health, and is provided in the form of a single use dosage as powder or granules. In the lyophilized effervescent biopesticide granule production method (10), biopesticide is used as the starter material and milk is used as the surfactant.

Abstract: This invention is related to sample preparation by a tissue differentiation method based on surface-enhanced Raman scattering (SERS) which enables fast and accurate pathological identification for tissue differentiation by means of surface-enhanced Raman scattering. The preparation of the sample includes homogenising a tissue sample by adding liquid nitrogen (104), crushing the frozen tissue and bringing it to a liquefied form (105).

Abstract: The present invention relates to synthesis of oligonucleotide mediated gold core- silver shell nanoparticles and testing their SERS performance. A Raman reporter molecule and twelve-base long oligonucleotide are simultaneously attached on gold nanoparticles and a silver layer is deposited on the modified gold nanoparticles. The SERS performance of gold core- silver shell nanoparticles (CSNPs) is much greater than the CSNPs prepared without oligonucleotides and the same size non-modified gold nanoparticles after silver staining.

Abstract: The present invention relates to a surface scanning system, which enables obtaining three dimensional models of the geometries of the objects particularly having shiny or specular surfaces, and which comprises at least one light source, a moving mechanism that enables the light source to move relative to the object to be scanned, at least one camera, a moving mechanism that enables the camera to move relative to the object to be scanned, a moving mechanism that enables the object to be scanned to move in order for it to be viewed from different angles, at least one controller that controls the light source, camera and the moving mechanisms.
