Abstract: Nanosensors have widely emerged as a growing industry for development and innovations over the last decades. It has influenced all the strata’s involving chemical, biological, electronics, and robotics, military, astronomical and environmental fields of interest. First synthetic Nanosensors were built by researchers at Georgia Institute of Technology in 1999. It basically have three method of construction: top-down lithography, bottom-up assembly, molecular self assembly including innovations: using semiconducting wires, material found in blue crabs, CNT’s, photonic devices. They are built on nanoscale whose purpose is mainly to obtain data on atomic scale and transfer it into data easy to analyze. This has outreached great achievements by providing the world with great newer facilities as they are widely used in biological world for detecting cancers, asthma attacks, tumors, specific DNA in order to recognize explicit genetic defects, military applications, to detect minute quantities of explosives, bioagents, chemicals, toxins, and other dangerous materials in air and water, for assisting astronauts on space missions as their size and weight of the systems are constrained. Nanotechnology is the building field which has great potentials of innovations. Some of them under work and those which can be brought under vision in future are Graphene based gas sensors, cigarette smoke sensor, bomb detection, nanorobotics, aiding drug manufacturing by detecting minute flaws in drugs and improving its production, researchers has also developed new method to control nanoscale diamond sensors which allows to monitor small changes via magnetic field and neurons transmitted electrical signals. Key growth controllers of nanosensors are opportunity for improved sensitivity and ability to detect multiple chemical compounds concurrently. This field has a great vision for future development and enhancing technologies to a new level.
