Scientists have made a major breakthrough in the field of quantum sensing, using tiny diamonds to create complex three-dimensional structures that can measure temperature and other physical properties with unprecedented accuracy.
The research team used a technique called multiphoton lithography (MPL) to fabricate intricate microscale structures from a special type of resin containing nanodiamonds. These nanodiamonds are made up of nitrogen vacancies, which are tiny defects in the diamond’s crystal structure that behave like tiny magnets.
When exposed to light, these nanodiamonds emit a specific signal that can be detected by scientists. By using this signal, researchers can measure the temperature and magnetic properties of their surroundings with incredible precision.
The team created a series of complex three-dimensional structures using MPL, including a triply periodic minimal surface (TPMS) known as a gyroid. This structure is made up of interconnected networks of tiny tubes that resemble a sponge-like material.
By filling these tubes with nanodiamonds and then measuring the signal emitted by the nanodiamonds, scientists were able to create a map of the temperature distribution within the TPMS. This allowed them to measure temperatures with an unprecedented level of accuracy, even in areas where traditional sensors would struggle to penetrate.
The implications of this research are huge. For example, scientists could use these tiny diamond-based sensors to monitor the health of living cells or track the movement of molecules in complex biological systems.
In addition to temperature measurement, the nanodiamonds can also be used to detect magnetic fields and other physical properties. This opens up a wide range of possibilities for applications such as biomedical imaging, materials science, and even quantum computing.
The researchers believe that their technique has the potential to revolutionize the field of quantum sensing, enabling scientists to make new discoveries and advance our understanding of the world around us.
