The impact of electrochemistry on micro- and nanorobot design

Nanowerk.com - 16 мая, 2017 - 10:56
A recent review article highlights the role of electrochemistry in synthesizing materials for self-powered micro- and nanodevices; the aspect of charge transfer and changes in electrochemical potentials for locomotion; control of self-propelled motion using electrochemistry and electric fields; and possible applications in electrochemical sensing and energy generation using micro- and nanoscale motion. The authors discuss various electrochemical techniques, which allow for the fabrication of large amounts of micro/nanorobots from diverse materials, with and without the use of templates.

Quantum reservoir for microwaves

Nanowerk.com - 15 мая, 2017 - 18:17
In a recent experiment, a microwave resonator, a circuit that supports electric signals oscillating at a resonance frequency, is coupled to the vibrations of a metallic micro-drum. By actively cooling the mechanical motion close to the lowest energy allowed by quantum mechanics, the micro-drum can be turned into a quantum reservoir - an environment that can shape the states of the microwaves.

Nano fiber feels forces, hears sounds made by cells

ScienceDaily.com: Nanotechnology News - 15 мая, 2017 - 18:16
Engineers have developed a miniature device that's sensitive enough to feel the forces generated by swimming bacteria and hear the beating of heart muscle cells. The device is a nano-sized optical fiber that detects forces down to 160 femtonewtons and sound levels down to -30 decibels. Applications include measuring bio-activity at the single cell level, or ultra-sensitive mini stethoscopes to monitor cellular acoustics in vivo.
