Researchers in the United States have developed a new method for controlling the brain circuits associated with complex animal behaviours, using genetic engineering to create a magnetised protein that activates specific groups of nerve cells from a distance.

Nanobiotechnology is emerging very promising to investigate novel methodologies for managing COVID-19 pandemic/endemic successfully. In this direction, experts have explored the opto-electro-magnetic nanosystem to detect the SARS-CoV-2 virus using a biosensing approach. Such optical, electrical, or magnetic biosensors function based on geno-sensing and immune-sensing has detected the SARS-CoV-2 virus selectively at a very low level. These efficient-miniaturized biosensors can be operated using a smartphone and promoted for clinical application for early-stage diagnostics of COVID-19 infection. The successful integration of these SARS-CoV-2 virus sensors with AI and IoMT enables virus detection at point-of-location and sharing of bioinformatics with the medical center at the same time for timely therapeutics decision. This approach is also useful for tracking tasks and managing COVID-19 infection according to patient infection profiling. To avoid human-to-human SARS-CoV-2 virus transmission, experts have developed stimuli-responsive nanotechnology enable which can not only trap aerosol of virus size but can eradicate viruses on applying external stimulation for example nanoenable photo-sensitive virus degradation. Various types of clothes containing nanoparticles have demonstrated SARS-CoV-2 virus trapping and eradication successfully [2,9]. However, significant attention is required to increase the production and distribution of these masks for public use.

Controlling movement in these tiny machines requires the researchers to shine a laser on minuscule light-sensitive circuits on their backs, which propels their four legs forward. They’ve been designed to operate in all manner of environments such as extreme acidity and temperatures. One of their chief purposes, the researchers say, could be to investigate the human body from the inside.
Fifty years of Moore’s law scaling in microelectronics have brought remarkable opportunities for the rapidly evolving field of microscopic robotics. Electronic, magnetic and optical systems now offer an unprecedented combination of complexity, small size and low cost, and could be readily appropriated for robots that are smaller than the resolution limit of human vision (less than a hundred micrometres). However, a major roadblock exists: there is no micrometre-scale actuator system that seamlessly integrates with semiconductor processing and responds to standard electronic control signals. Here we overcome this barrier by developing a new class of voltage-controllable electrochemical actuators that operate at low voltages (200 microvolts), low power (10 nanowatts) and are completely compatible with silicon processing. To demonstrate their potential, we develop lithographic fabrication-and-release protocols to prototype sub-hundred-micrometre walking robots. Every step in this process is performed in parallel, allowing us to produce over one million robots per four-inch wafer. These results are an important advance towards mass-manufactured, silicon-based, functional robots that are too small to be resolved by the naked eye.
