Nanotechnology is an emerging field with an interdisciplinary research. It deals with tailoring of particles in the range of 1-100 nm to attain unique properties from their bulk counterpart. The nanoparticles can be synthesized by various means. Chemically synthesized nanoparticles utilize toxic chemicals as reducing agents, which makes it a not so favored method of synthesis. Therefore, green synthesis came into light, which makes use of a reducing biological agent to reduce metals to nanoparticles. Repeated and improper devouring of antibiotics to combat infectious diseases leads to drug or even multi-drug resistant strains, which pose a significant threat to society. Silver nanoparticles seem to be the savior due to their antimicrobial activity against various pathogens. In this study, technology seeds extract is utilized to reduce silver nitrate solution to silver nanoparticles. The synthesized nanoparticles were then characterized and checked for their antimicrobial activity and their mode of action. Nanotechnology is the manipulation of matter on a near-atomic scale to produce new structures, materials and devices. The technology promises scientific advancement in many sectors such as medicine, consumer products, energy, materials and manufacturing. Nanotechnology refers to engineered structures, devices, and systems. Nanomaterials have a length scale between 1 and 100 nanometers. At this size, materials begin to exhibit unique properties that affect physical, chemical, and biological behavior. Researching, developing, and utilizing these properties is at the heart of new technology. Workers within nanotechnology-related industries may experience exposure to uniquely engineered materials. This includes novel sizes, shapes, and physical and chemical properties. Occupational health risks associated with manufacturing and using nanomaterials are not yet clearly understood. Minimal information is currently available on dominant exposure routes, potential exposure levels, and material toxicity of nanomaterials. National Nanotechnology Initiative.
Nanotechnology is science, engineering, and technology conducted at the nanoscale, which is about 1 to 100 nanometers. Physicist Richard Feynman, the father of nanotechnology. This is the study and application of extremely small things and can be used across all the other science fields, such as chemistry, biology, physics, materials science, and engineering.
The ideas and concepts behind nanotechnology started with a talk entitled “There’s Plenty of Room at the Bottom” by physicist Richard Feynman at an American Physical Society meeting at the California Institute of Technology on December 29, 1959, long before the term nanotechnology was used. Over a decade later, in his explorations of machining, Professor "Taniguchi" coined the term nanotechnology.
Fundamental concepts Nanotechnology. Medieval windows are an example of how nanotechnology was used in the pre-modern era.
It’s hard to imagine just how small nanotechnology is. One nanometer is a billionth of a meter, or 10-9 of a meter. Here are a few illustrative examples:
On a comparative scale, if a marble were a nanometer, then one meter would be the size of the Earth
This is the ability to see and to control individual atoms and molecules. Everything on Earth is made up of atoms—the food we eat, the clothes we wear, the buildings and houses we live in, and our own bodies.
In fact, it is the impossible to see with the microscopes typically used in a high school science classes. The wide range of microscopes needed to see things at the nanoscale were invented in the early 1980s ages.
Once scientists had the right tools, such as the scanning tunneling microscope and the atomic force microscope, the age of nanotechnology was born.
Although modern nanotechnology is quite new, nanoscale materials were used for centuries. Alternate-sized gold and silver particles created colors in the windows of medieval churches hundreds of years ago. The artists back then just didn’t know that the process they used to create these beautiful works of art actually led to changes in the composition of the materials they were working with.
Today scientists finding a wide variety of ways to deliberately make the materials at the nanoscale to take carefully of their enhanced properties such as higher strength, lighter weight, increased control of light spectrum, and greater chemical reactivity than their larger-scale counterparts.
