This work proposes a miniaturized system able to perform multiple cell capture followed by cell-type selective release from a biochip surface. Unlabelled lymphocytes were first specifically captured onto a DNA array by antibody-DNA conjugates. The immobilized cells were subsequently released under spatiotemporal control within local heating generated by intense Surface Plasmon Resonance (SPR) produced by laser illumination.
