LASER: Light Amplification by the Stimulated Emission of Radiation or LASER in short is a device that concentrates light into a narrow beam. The light thus produced is intense, coherent and unidirectional. LASER has a wide variety of application in eye surgery (LASIK), high-speed metal cutting machines, CD players, hair replacement et al.
Ligand: Ligand is a term used for referring to small molecule or functional group that is bound to other larger molecule, such as carbohydrate, protein or lipid, inducing a biological activity.
LINAC: A Linear Accelerator (LINAC) is a particle accelerator commonly used for external beam radiation treatments of cancer patients. LINAc uses microwave technology to accelerate charged particles.
Linux: Linux is a free Unix-type OS (operating system), the source code for Linux is freely accessible to all users.
Liquid Nitrogen: Liquid Nitrogen is used for a variety of applications. This include freezing of perishable foods, rigidifying plastics and rubbers, preservation of biological materials, producing low temperatures required in cryosurgery et al. The properties of Liquid Nitrogen -noninflammable, odourless, colourless, inert, non-corrosive and very cold makes it a good choice for variety of applications.
Lab-on-a-Chip: Lab-on-a-Chip devices have made it possible to conduct laboratory experiments on a small-scale and outside the confines of a laboratory. With Lab-on-a-Chip devices, medical diagnostics, chemical synthesis, studying complex cellular processes has just become easier.
Leukaemia: Leukaemia is a cancer of the white blood cells mainly affecting children and young people.
