Planar nanoneedles on-chip for intracellular measurements
2005 (English)In: Micro Total Analysis Systems - Proceedings of MicroTAS 2005 Conference: 9th International Conference on Miniaturized Systems for Chemistry and Life Sciences, Transducers Research Foundations, 2005, Vol. 1, 400-402 p.Conference paper (Refereed)
We present for the first time a functional planar SiN-nanoneedle system for intracellular mass transport and in vivo electrophysiological measurements on-chip. Though several micro- or nanoneedles for cell research have been described in literature, no needles of this small size equipped with nanosized inner channels or electrodes have been reported. A propidium iodide assay verifies the excellent penetration performance of the nanoneedles with diminished leakage from the cell after insertion and release of the needle from HL60-cells. Hollow needles connected to on-chip sub-picoliter electrochemical dosing systems are in development.
