These interactions also play a role in electronics, making materials such as graphene and quantum dots very useful for microcomputers and communication equipment. Nanoscale materials provide a smaller area for electron mobility. Perhaps most importantly, in current research, at the nanoscale, you are the scale of biology. "Most content is embedded in the traditional products that we purchase, it is not even considered," says Mirkin. "There is no intrinsic good and evil in simplifying the problem, the question is what they did and what they used. Did you consider the appropriate security analysis and impact, considering the application? I think that we are doing very well. "

The current 2D interface for nanoscale design is based on the interface of the traditional keyboard and mouse of the 1990s. They often rely on command line based data manipulation which is very intuitive. This will cause the nanoscale designer to raise the threshold excessively for entry. Designing drugs is similar to designing complex bonds (molecules) of complex locks (active protein sites). Solving 3D puzzles with keyboard and mouse is inefficient, inefficient, and very irritable. Next generation interfaces like VR can achieve simpler, faster, and better designs on the nanometer scale. VR not only improves the workflow of "advanced users" but also makes it easier to use, democratizes nanoscale designs, and opens up the market for many amateur designers.

Although manufacturing nanoscale transistors is very useful for increasing functional density, it has drawbacks when designing analog circuits. Nanoscale transistors can only withstand very small supply voltages. For example, circuits designed using state-of-the-art CMOS transistors can only operate with supply voltages up to about 1 V. Although the conventional analog circuit operates at maximum + 5 V / -5 V, the stable power supply voltage drops to 5 V, 3.3 V, 1.8 V to 1.2 V, future device prediction is 0.5 V, It decreases to 0.2 V. Supply voltage also helps digital design reduce energy consumption. However, with analog circuits, lowering the power supply voltage will increase the sensitivity to noise and interference, resulting in poor signal quality. To increase the difficulty, nanoscale transistors also show more mismatch, resulting in random offset errors, more flicker (1 / f) noise, and poor gain performance.
