The freeze-dried coffee chips retain the original flavor of coffee well. Due to its loose and porous internal structure and fast dissolution rate, it is a "instant coffee" that is convenient to measure and can easily control the concentration of the beverage.
US Scientist Develops "Viral Transistor" with Tobacco Mosaic Virus
Computer viruses and mobile phone viruses are a major concern for security. However, some biologically significant viruses could hold the key to creating next-generation electronic components. In fact, American scientists have already made progress by using the tobacco mosaic virus to develop "virus transistors" that operate at incredibly high speeds.
The speed of a transistor directly affects how fast a chip can process data. If many of these "viral transistors" can be integrated into a single chip, it could significantly boost the performance of electronic devices. For instance, a digital camera currently takes a few milliseconds to display a photo, but with this new technology, the time could be cut down to just microseconds.
Recently, researchers from the University of California, Los Angeles, published their findings in *Nature Nanotechnology*. They coated the surface of the tobacco mosaic virus — which is about 30 nanometers long — with tiny platinum nanoparticles. Each virus had around 16 platinum particles on its surface. The virus was then embedded in a polymer grid and placed between two electrodes, forming a structure similar to a traditional transistor.
When a voltage is applied, each platinum particle releases an electron to the virus's protein, turning the transistor "on." When the voltage drops, the electrons return to the platinum, switching the transistor "off." This entire process only involves movement over about 10 nanometers and takes just 100 microseconds.
Although this breakthrough is promising, it's still far from being used in real-world chips. Scientists are now working on connecting multiple "viral transistors" together and aim to create a prototype with millions of them within the next four years. This research could one day lead to faster, more efficient electronics powered by nature’s own building blocks.
