Optical tweezers for living cells
Arthur Ashkin was recognized for inventing "optical tweezers that grab particles, atoms, viruses and other living cells with their laser beam fingers." Most notably in 1987, Ashkin used the novel tweezers to capture living bacteria without causing harm to them resulting in the tools being widely used in the machinery of life experimentation.
Science fiction has become a reality. Optical tweezers make it possible to observe, turn, cut, push and pull with light. In many laboratories, laser tweezers are used to study biological processes, such as proteins, molecular motors, DNA or the inner life of cells.#NobelPrize pic.twitter.com/tWK55J4VcP

Shortest and most intense laser pulses
Meanwhile, Gérard Mourou and Donna Strickland were acknowledged for their crucial work in paving the way "towards the shortest and most intense laser pulses ever created by mankind." The duo conceived of a brilliant approach to creating ultrashort high-intensity laser pulses without destroying the amplifying material.

The physicists' newly-invented powerfully-efficient technique was named chirped pulse amplification (CPA). It quickly became a standard for subsequent high-intensity lasers finding many varied applications including in the life-changing corrective eye surgeries that are so common today.

The event also marks the third time in 55 years that a woman has won the Nobel Prize in physics. The prize now brings the total number of female recipients of this particular Nobel to three.
Strickland said she was honored by the nomination but also emphasized the need for more female participation and acknowledgment in the field. "I thought there might have been more but I couldn't think," said the physicist during the ceremony.
"Obviously, we need to celebrate women physicists because we're out there. Hopefully, it will start to move forward at a faster rate," added Strickland. The other two notable women winners were Maria Goeppert-Mayer, awarded in 1963, and Marie Curie, awarded in 1903.
“First of all, you have to think it is crazy!”
