Biotphex

Project duration 2004-2005. The project aims to develop the two-photon excitation (TPX) method for the measurement of fluorescence from antibody labels on the surface of micro- and nano-sized carrier particles, The proposed two-photon excitation (TPX) method which is based on fluorescence caused in micro-volumes by two-photon excitation combines the most advanced technology in micro-fluidistics, micro-mechanics, laser scanning microscopy and flow cytometry applications. The method will enable multiplex identification of antibody labels and the project will develop new antibodies suitable for high sensitivity assays. The current microchip laser will be developed to increase pulse frequency and reduce pulse duration. The TPX plate reader will allow multiplexed analysis through the use of fluorescent labeling agents, which have different emission wavelengths. The micro plate to be used will significantly reduce reagent requirements and dispense with the multiple washing currently required in conventional methods. The project will extend the method to be suitable for cell counting by combining it with oxygen up-take measurement technologies and an appropriate laser model. The objective of the project is to produce pre-production models to allow large-scale screening of a biomaterials and pharmacological compounds, which can be carried out in, distributed centers, improving the logistics involved in current bio-assays.

Lasers for microprocessing and diagnostics

During 2005-2007 four Lithuanian companies working with lasers (Standa ltd, Ekspla ltd, Light Conversion ltd, Optida ltd) gathered their knowledge and resources to develop a market competitive laser for microprocessing and push local laser technologies to the next level. Project was supported by EU structural funds. The matters of precise adjustment, micro and nano positioning were trusted to Standa. First results were achieved soon after: assembled nanosecond laser systems with average power of 15W, femtosecond and picosecond lasers with 10W average power and up to 100kHz rate. Various properties generating schemes were tested. Harmonics generating tests took place. Tested new laser emission resistant coating vaporization technologies. Femtosecond laser was tested in theraHz emitting schemes. Picosecond and nanosecond laser schemes were tested in metal cutting, drilling and silicon processing.

Ultra-wideband measurement systems

The goal of this project was to develop a less costly and more efficient equipment for scanning and calibrating ultra-wideband antennas. Standa developed and manufactured XYZ precise positioning systems for various antennas.
