Nanosensors
WHAT ARE NANOSENSORS?
Another wonderful invention of nanotechnology are nanosensors these are biological, chemical or surgical sensory edges or points which are used to detect and transfer nano particle information to the other devices such as microscopic/macroscopic world. There basic purpose is to develop medical nano products such as silicon computer chips and nano robots fabrications. Now a days there are many techniques which claims to develop nanosensors which involves top-down lithography, molecular self-assembly and bottom-up assembly approaches. HOW NANOSENSORS WORK?
Nanosensors works with their special sensation ability which can detect information and data .there arrangement is like ordinary sensors but the major difference between sensors and nanosensors is that nano sensors are developed at nanoscalae which makes them distinguished from ordinary ones. Nano sensors can accurately identify specific cells or the parts of the body having any deficiency. They work by calculating and measuring ups downs and changes, displacement, dislocations, concentration, volume, acceleration, external forces pressure or temperature of each cell in the living body. Many nanosensors are designed to differentiate between normal and abnormal cells such as sensors for detecting cancer in living body, molecular controllers to deliver medicines in the human body. They are also enabling to detect macroscopic changes that appear from the external interactions and communicate these variations to the other nanocomponents working along.
NANOSENSORS EXAMPLE:
The most famous example of nanosensors which includes use of fluorescence characteristics of cadmium selenide quantum dots to discover tumor in the body. These small dots are injected in the infected area of the human body, so doctors could determine the exact stage of cancer or tumor. Nanosensors are also used in DNA test to recognize the similar properties of two blood cells. Circuit integrations are also performed
