Much like the Jedis in Star Wars use the force to control objects from a distance, scientists can use light or optical force to move very small particles.
The inventors of this ground-breaking laser technology, known as optical tweezers , were awarded the 2018 Nobel Prize in physics.
Optical tweezers are used in biology, medicine and materials science to assemble and manipulate nanoparticles such as gold atoms. However, the technology relies on a difference in the refractive properties of the trapped particle and the surrounding environment.
Now scientists have discovered a new technique that allows them to manipulate particles that have the same refractive properties as the background environment, overcoming a fundamental technical challenge.

New Laser Number Generator System Could Enable More Secure Data Encryption
Written by AZoOpticsFeb 26 2021
A new system created by an international group of researchers exhibits the ability to generate random numbers more than 100 times quicker than existing technologies, thus opening the door to quicker, cost-effective, more secure data encryption in the present-day’s digitally connected world.

The random number generator system was collaboratively designed by researchers from Nanyang Technological University, Singapore (NTU Singapore), Trinity College Dublin, and Yale University and made in NTU.
Random numbers serve a range of purposes, for example, producing data encryption keys and one-time passwords (OTPs) in day-to-day processes, such as e-commerce and online banking to boost up their security.

An international team of scientists has developed a system that can generate random numbers over a hundred times faster than current technologies, paving the way towards faster, cheaper, and more secure data encryption in today s digitally connected world.
The random generator system was jointly developed by researchers from Nanyang Technological University, Singapore (NTU Singapore), Yale University, and Trinity College Dublin, and made in NTU.
Random numbers are used for a variety of purposes, such as generating data encryption keys and one-time passwords (OTPs) in everyday processes such online banking and e-commerce to shore up their security.
