Kelvin Probe Force Microscopy in Bionanotechnology: Current Advances and Future Perspectives

Advanced Materials, EarlyView.
Kelvin probe force microscopy (KPFM) enables the nanoscale mapping of electrostatic surface potentials. While widely applied in materials science, its use in biological systems remains emerging. This review presents recent advances in KPFM applied to biological samples and provides a critical perspective on current limitations and future directions for

An ultralow noise preamplifier for low frequency noise measurements

Review of Scientific Instruments, 2009
Low frequency noise measurements are among the most sensitive tools for the investigation of the quality and of the reliability of semiconductor devices. The sensitivity that can be obtained depends on the background noise of the low noise preamplifier coupled to the device under test (DUT) that, at very low frequencies, is dominated by flicker noise ...

Low noise and low cost neural amplifiers

2007 14th IEEE International Conference on Electronics, Circuits and Systems, 2007
Extracellular neural signal acquisition requires low noise, high gain, low power, and low cost amplifiers. This paper presents amplifiers with a simple architecture that ensures a good compromise among these characteristics. We present three amplifiers based on the same architecture, in which the first stage is a differential pair, respectively based ...
