A Biosensor is a device that measures biological or chemical reactions by generating signals proportional to the concentration of an analyte in the reaction. Biosensors are employed in applications such as disease monitoring, drug discovery, and detection of pollutants, disease-causing micro-organisms and markers that are indicators of a disease in bodily fluids (blood, urine, saliva, sweat). it consists of the following components.
Analyte: A substance of interest that needs detection. For instance, glucose is an ‘analyte’ in a biosensor designed to detect glucose.
Bioreceptor: A molecule that specifically recognises the analyte is known as a bioreceptor. Enzymes, cells, aptamers, deoxyribonucleic acid (DNA) and antibodies are some examples of bioreceptors. The process of signal generation (in the form of light, heat, pH, charge or mass change, etc.) upon interaction of the bioreceptor with the analyte is termed bio-recognition.
Transducer: The transducer is an element that converts one form of energy into another. In a biosensor the role of the transducer is to convert the bio-recognition event into a measurable signal. This process of energy conversion is known as signalisation. Most transducers produce either optical or electrical signals that are usually proportional to the amount of analyte–bioreceptor interactions
Renewable energy is energy derived from natural sources that are replenished at a higher rate than they are consumed. Sunlight and wind, for example, are such sources that are constantly being replenished. Renewable energy sources are plentiful and all around us.Fossil fuels - coal, oil and gas - on the other hand, are non-renewable resources that take hundreds of millions of years to form. Fossil fuels, when burned to produce energy, cause harmful greenhouse gas emissions, such as carbon dioxide.

The Neutrino energy of a neutrino depends on the process that formed it. Because neutrinos have no charge, there’s no way to use electric fields to accelerate them and give them more energy, the way scientists can do with particles such as protons. More energetic reactions will create more energetic neutrinos. These are great for scientists, because particles with more energy are more likely to interact and leave traces. They’re more likely to be stopped by regular matter and transfer that energy to something else (other particles) that detectors can pick up.
Geothermal energy is the heat from the Earth and it's a clean and sustainable. Resources of geothermal energy range from the shallow ground to hot water and hot rock found a few miles under the surface of the earth, and down even deeper to the extremely high temperatures of molten rock named magma.
