Abstract

This work presents the fabrication of hourglass-shaped aperture by applying twostage CO2 laser pulses on glass substrate to control the size of the aperture to 1- 10μm, and applies the fabricated aperture to measure ion-channel activities and to trap single cells in array configuration. First stage laser pulses with longer duration was utilized to generate apertures larger than 10μm, and a series of shorter duration laser pulses was added for maintaining the glass reflow to reduce its diameter. This easy fabrication procedure can be operated without complicated micro-fabrication process for applications of single-cell analysis.
