A nano-camera that captures the chemical process in real time
Cambridge: Scientists at the University of Cambridge have developed a tiny mini-nano camera made of molecular glue. It helps in real time observation of chemical reactions.
For this, they have developed very small semiconductor nanocrystals, also called quantum dots. It is made up of gold nanoparticles that are bonded to a special kind of molecular glue. This glue has been dubbed ‘Cucurbital (CB)’. When mixed with water, they combine in seconds, and their use is such that chemical reactions can be observed with them in real time.
This camera is built inside a semiconductor. The process of electron transfer is similar to that of photosynthesis. Now the nanoparticles act as sensors and work in a spectroscopic way. This way the camera is able to see the chemical process. In this way we will be able to know the chemical reactions about which there is theoretical information but no concrete evidence has been found so far.
In this way, chemical processes and molecules can be viewed and tested in many ways. On the other hand, it has many practical uses. Details of the study are published in the weekly scientific journal Nature. The invention was invented by Dr. Orn Sherman, a professor at the Department of Chemistry in Cambridge, and Dr. Yusuf Hameed. He says it was very difficult to make and assemble nanostructures.
It was necessary to devise a reliable method for connecting two types of semiconductors. For this, the need for a curative or CB was felt. It is a molecular glue that can bind both quantum dots and gold nanoparticles. The first phase observed the chemical process of photocatalytic licenses and the second observed the electron transfer thanks to light.
The results have been observed through spectroscopy and thus chemical reactions have been observed in real time.
