Micro pulsed radio-frequency electroporation chips.
Electroporation (EP) is one of the most important physical methods in biotechnology, which employs electrical pulses to transiently permeabilize cell membranes. In this study, a new micro pulsed radio-frequency electroporation cell (microPREP) chip was fabricated using a lift-off technique and SU-8 photolithography. The biological tests were carried out using three different plant protoplasts (...
متن کاملCurrent-induced membrane discharge.
Possible mechanisms for overlimiting current (OLC) through aqueous ion-exchange membranes (exceeding diffusion limitation) have been debated for half a century. Flows consistent with electro-osmotic instability have recently been observed in microfluidic experiments, but the existing theory neglects chemical effects and remains to be quantitatively tested. Here, we show that charge regulation a...
متن کاملEffect of the driving frequency on the emission characteristics of a radio-frequency glow discharge excitation source boosted by the introduction of a d. c. bias current.
In a radio-frequency-powered glow discharge lamp, a d.c. bias current which is driven by a self-bias voltage can lead to an enhancement of the emission intensities excited by the plasma. The driving frequency of the r.f. plasma is an important parameter to determine the self-bias voltage; lower r.f. frequencies induce greater self-bias voltages. The effects of the bias current introduction on t...

متن کاملEffects of low level pulsed radio frequency fields on induced osteoporosis in rat bone.
Effect of modulated pulsed electromagnetic fields (PEMFs; carrier frequency, 14 MHz. modulated at 16 Hz of amplitude 10 V peak to peak) on sciatic neurectomy induced osteoporosis in rat femur and tibia resulted in statistically significant increase in bone mineral density, and deceleration in bone resorption process and consequently further osteoporosis in rat bone. These results suggest that s...
