Photonic Device to Enable Bio Experiments in Space

Facebook X LinkedIn Email
Researchers at the Indian Institute of Science (IISc) and the Indian Space Research Organization have developed a modular, self-contained device to cultivate micro-organisms. The work could enable biological research in outer space. Using an LED and photodiode sensor, the device can track the growth of a bacterium called "Sporosarcina pasteurii" over the course of several days, and with minimum human involvement. The LED and photodiode sensor combination can track growth by measuring the optical density or scattering of light, similar to spectrophotometers. A modular,...Read full article

    photodetector
    A photodetector, also known as a photosensor or photodiode, is a device that detects and converts light into an electrical signal. Photodetectors are widely used in various applications, ranging from simple light sensing to more complex tasks such as imaging and communication. Key features and principles of photodetectors include: Light sensing: The primary function of a photodetector is to sense or detect light. When photons (particles of light) strike the active area of the photodetector,...
    integrated photonics
    Integrated photonics is a field of study and technology that involves the integration of optical components, such as lasers, modulators, detectors, and waveguides, on a single chip or substrate. The goal of integrated photonics is to miniaturize and consolidate optical elements in a manner similar to the integration of electronic components on a microchip in traditional integrated circuits. Key aspects of integrated photonics include: Miniaturization: Integrated photonics aims to...
