Researchers from the Madras Institute of Indian Technology (IIT) have done something incredible – they have shown the possibility of creating a biocompatible laser working from a carrot, using a scientific process first discovered by the famous Indian scientist Sir CV Raman who won The Nobel Prize for Physics in 1930! This development by IIT Madras researchers is the first of its kind in the world.
Not only does the laser made of carrots be bi-friendly, but the system that is being developed is also robust, reliable and has a good and linear response to & # 39 ; r temperature.
This perception of the team could help to promote science in the fields of scientific and industrial research on spectroscopy and optical sensation.
Features of bio-friendly lasers IIT Madras is developing from a carrot:
- A natural and fully biocompatible system, which can be used with other bio-entities to detect sensor based on the proposed laser
- Easy and safe to use and use
- Strong and extremely reliable as the delay mode is mounted on a specific wavelength by the vibrant method of Raman
- The kitchen laser & # 39; This is a very good and linear response for temperature that could also be used for temperature sensation
What is a laser and how does it work?
Light Improvement through Impulsive Radiation Emission, more well-known as LASER, is one of the most important findings of the 20th century.
Lasers are currently sources of light with incredible properties such as a high degree of orientation and accuracy.
Laser is created when electrons are in some special materials absorb energy and are exciting. These electrons emit light & light particles; or photons when they return to their original condition. The photons are coherent, which means the light is powerful and sudden.
These mitigating materials are usually stable and semiconductor materials, such as Nd-YAG, which are expensive, and include environmental issues during production and / or use.
Lares are essential requirements in a variety of products and technologies, including communication, lithography, medicine, military operations, scientific research, engineering, exhibitions and data storage.
In this research by IIT Madras, the Raman process with the cellulose network was used to show a special class of lasers of random lasers & # 39; in carrots.
Who was everyone involved in this research?
This research was undertaken by a team that includes Prof C Vijayan, Physics Department, IIT Madras, and Dr Sivarama Krishnan, Assistant Professor, Physics Department, IIT Madras, together with Venkata Siva Gummaluri, PhD Research Scholarship , Department of Physics, IIT Madras.
Why is bio-friendly technology important now?
"Now no move towards developing green, sustainable materials for different applications, including photonics. The need for green photonic technologies is evident in the current times where sustainability, bio-compatibility and radiation are crucial, "he said. Professor C Vijayan, talking about the importance of this research by IIT Madras.
Science behind IIT Madras's research lines have to make a carrot
Organic chemical leakage sources have been around for decades, as long as semiconductor sources.
Random Lasers (RL), for example, have traditionally used plasmona or dialectric dispersors, and they gain media such as chemical colors and fluorescent polymers.
Although the traditional polymers used are toxic and non biodegradable, the search has been available for more eco-friendly fluorescent polymers.
Cellulose fibers, for example, have been shown to facilitate multiple spread of phones, suggesting the possibility of a bio-compatible organic / ecosystem dispersion medium.
As biocompatibility and sustainability refers to bio-derivative materials, IIT Madras's research team looked at biological molecules as likely dropping sources.
"We're very pleased to see singing in fresh carrots, because of the carotene and cellulose found in them. We have successfully demonstrated the losing of CW-laser CW-laser fixed models, using Raman activity of naturally occurring garoten and multiple dispersion due to sulphos in carrots, "said Gummaluri, a PhD student.
"Organic bio-pigments are like Carotenoids found in carrots and bovines found in the chlorophyll are active active media because of their visible light absorbing images, "said Dr Sivarama Krishnan, elaborating on their research.
"Although the The quantum product of fluorescence of carotenoids is much less compared to standard organic laser dyes, the vibrant spectrum can even be obtained with very low concentrations of carotenoids. The garotenoid research team has chosen naturally, as a source of delay, "he added.
Carrots, as well as having carotenoids, also have cellulose fibers that contribute to multiple waste of photons and consequential optical reinforcement for Raman random collection. They were not wrong in their expectation.
