Science Daily May 22, 2024 High-aspect-ratio mechanical resonators are pivotal in precision sensing. However, fabrication challenges and high computational costs have limited the length-to-thickness ratio of these devices. An international team of researchers (The Netherlands, USA – Brown University) developed nanomechanical resonators that extend centimeters in length yet retain nanometer thickness. They expanded the design to include more computationally intensive centimeter-scale design optimization. Their approach ensured high-yield realization, experimentally confirming room-temperature quality factors close to theoretical predictions. According to the researchers synergy between nanofabrication, design optimization guided by machine learning, and precision engineering opens a solid-state path to room-temperature quality […]

Innovative silicon nanochip can reprogram biological tissue in living body
Science Daily December 10, 2021 A team of researchers in the US (Indiana University, Purdue University, industry, Veterans Administration Medical Center, University of Chicago) has developed a silicon device that can change skin tissue into blood vessels and nerve cells has advanced from prototype to standardized fabrication. The technology, called tissue nano transfection, is a non-invasive nanochip device that can reprogram tissue function by applying a harmless electric spark to deliver specific genes in a fraction of a second. The nanofabrication process typically takes five to six days, and in vivo takes 30 min. In laboratory studies, the device successfully […]
