Nanotechnology Demystified Tools and Techniques

Having understood that nanotechnology deals with playing around with extremely minute things that are too little to physically see, you must be quite interested in finding out how exactly these materials, tiny as they are, are manipulated. Keep reading to find out how.

Firstly, before scientists can ever tamper with atoms and molecules they need to first be able to see them. Characterization is the means through which scientists are able to detect some of the To do this they basically use microscopes but not just any microscope, they engage special microscopes which are magnifying glasses for materials which work in various ways:

1. Scanning Tunneling Microscopy: this method employs a super-sharp probe tip to obtain an image of atoms by scanning through surfaces detecting intricate molecular makeup.

2. Atomic Force Microscopy: this method is quite similar to the first only that beyond merely acquiring a good view of nanoscale objects it also provides additional information about them such as their elasticity , magnetism , etc.

3. Electron Microscopy: this kind of microscopy provides detailed picture of the micro world by passing electrons through the the object it is scanning. There’s different kinds of electron microscopes they dissect the materials they set to observe and offer formidable insight of their internal structure.

4. Spectroscopy: this method utilizes light to tell apart nano-materials and identify some of their properties. Raman spectroscopy is prominent in this arena for it identifies molecules based on their vibrational fingerprint.

When it comes to creating nanotechnology there’s a bottom up and zeroing in approach. The former deals with self-assembly that entails building up nanotech using lithography, chemical vapor deposition or other methods to achieve this.

Lastly, I’d like to talk about computational modeling methods used to simulate nanoscale environments. Most scientists conduct virtual nano technological experiments virtually manipulate nano elements since acquiring the hardware to do so is quite costly.
