Abstract: A method and system for detecting, manipulating and isolating circulating tumor cells found in organic fluids comprising a simplified laser assisted transfer process. A liquid specimen of the organic fluid containing an enriched population of tumor cells and a population of non-tumor cells is spread onto a donor substrate with an interlayer comprising a semi-transparent polymeric adhesive tape. A fluorescent staining of at least one of the cell populations present in the liquid specimen is required to identify-using optical and fluorescence microscopy, the location of the cells to be manipulated and/or isolated. The laser beam energy is absorbed by the polymeric adhesive tape giving place to the formation of a blister that mechanically interacts with the liquid specimen and such interaction can induce the expulsion of a portion of the liquid specimen comprising the selected tumor cells or non-tumor cells, which can be a single cell or a cell cluster, towards the receiving substrate.

Abstract: The present invention relates to a method for creating electrical contacts in optoelectronic and electronic devices, including high and low concentration solar cells, thin films, organic light emitting diodes (OLED) and in general any device requiring the extraction or injection of a current by means of electrical contacts. The method comprises the following stages: (a) depositing the contact material on the final substrate through the laser induced forward transfer (LIFT) of said material from a donor substrate to the final substrate, preferably using a pulsed laser and (b) sintering the contact material using a laser source, preferably a continuous laser. The contacts thus created present excellent conductivity and adherence properties, as well as high height (thickness) to width ratios.
