What is NANO SCIENCE ? What is NANO TECHNOLOGY ?
Nano technology has huge historicalbackground although it got its speed in therecent years . The core concepts were introduced in the early50’s . The first ever concept was presented in 1959 bythe famous professor of physics Dr. RichardP.Feynman while explaining the creation ofmolecular machines with accurate atomicprecision.
MEDICAL APPLICATIONS Diagnosis Drug delivery Miniatured Mechanical surgery
ATOMIC FORCE MICROSCOPE Configured and manupulated at nanoscaleUsed to measure the particles of an elementor material at the smallest level i.e at nanometresEx: identification of cancer and other fatalbacterias.
WATER PURIFICATION Nano materials can purify water upto 99.9% with outaffecting the original flavour of water. Nano filtration plants are present in the developedcountries of the world.
TOXICITY DETECTORS These detectors detect the toxic chemicals and themeasurement of concentrated substances in theenvironment. These detectors are very useful and beneficial for thechemists in order to manage and reduce the toxicity ofchemicals.
DISPLAY AND AUDIO DEVICES “Nano pixelation” make the picture feel real. Frequency modulation in audio devices can benow digitized to Billionth bit of signals.Ex: LCD’s and LED’s
CHEMISTRY Exploring new Chemical reactions . Can study atoms and molecules more and moreeffectively at nano scale Properties of different substances can be found
DEFENCE APPLICATIONS Can be used as Spying Instruments. Reduces the loss of Life and Property. Reduces Man power in war.
Lack of employment in the fields of traditionalfarming ,manufacturing and industrial sector. At present Nano technology is most EXPENSIVEtechnology. Nano Pollution Nano bots can cause eventual health problems inthe bodies of consumers who use them because oftheir small size.
