Nanotechnology is technology created on the scale of individual atoms or molecules.
This is already creating new materials which are being mass produced and sold.

"The U.S., Russia and China are believed to be investing billions on nanoweapons research."[1]
Biochip
Hydrogels are a product of the “In Vivo Nanoplatforms” (IVN) program that DARPA’s Biological Technologies Office (BTO) launched in 2014 to develop implantable nanotechnologies.
The company Profusa is developing a nanoscale biochip made of hydrogels that can detect symptoms of an infection. Rather than being isolated from the body, the biosensors work fully integrated within the body’s tissue — without any metal device or electronics, thereby overcoming 'the foreign body response', the body’s attempts to reject it.
This hydrogel includes a specially engineered molecule that sends a fluorescent signal outside the body when it begins to fight infection. This signal can then be detected by a sensor attached to the skin that can then be sent to an app or even to a doctor’s website.
When it was first tested in 2018, this hydrogel was being used to measure glucose, oxygen and lactate levels. However, in March 2020, the company announced[2] that it was conducting a study to see if the technology could be used to detect respiratory diseases, including COVID-19.
