Ultrasound-assited micro-knife for cellular scale surgery


An ultrasound-assisted micro-knife with a 500nm-thick silicon nitride blade is described. The sharp blade can be operated to cut soft cells without lysing. The operation conditions are optimized by finite element analysis and experimental evaluation. For validation of the cutting precision Si<sub>x</sub>N<sub>y</sub> blades without and with ultrasonic… (More)
