Micro-barcodes for biological applications
Single cell labeling and tracking is an interesting field in cell biology. The growing development of small barcodes will allow studies at single cell behavior under optical microscopes. These codes have to fulfill special biological, optical and fabrication requirements. Nowadays, silicon microtechnologies advances allow fabricated structures at small dimension. In this paper, we show the design and fabrication of silicon and polysilicon barcodes based on standard MEMS technologies and their feasibility to be used for cell tracking and labeling.
