First knowing that what "nano" designates, which will help us to get the idea of how small the technology is, that bio-engineers are dealing with.
1 Nano meter= 1/10⁹ meter.
The bots are 5 to 500 nano-meters (or around 100 to 10’000 times smaller than a human hair).
 So, no doubt the technique is very sophisticated. MIT researcher Sangeeta bhatia and Geoffrey von Maltzahn are working with this.

Seeing the side effects that are caused by treatment process, the bio-engineer are searching for more healthy alternative. Though previously there was a little bigger version of nanobots called Microbots they were controlled through changing direction of magnetic field, but Nanobots are all automated and when injected into the body through blood stream, they search for the malignant tumors, though significant number of bot didn't make up to the target, but the ones which meets the target started heating the tissue through laser, then a second wave of nanobot are released which combine with the damaged tissue. Most important part is that it can target over 40 times higher doses of chemotherapeutics to tumors.

Gold nano-particles (shown below in blue), would passively accumulate in the tumor. then heating the nano-particles using a laser, thereby causing damage to the tumor tissue. The second wave of nano-particles (shown below in red) were engineered to bind to the damaged tissue, and would therefore accumulate at higher numbers there.

F1: Open Chrome's Help Center in a new tab or window.
CTRL + SHIFT + DELETE: Open the Clear Browsing Data window.

2. To print a specific portion of the page:  Just select the portion of lines, the right click over it, further click to the print option.

thus, only printing the selected lines.




3.Open a link in a new tab:  Though this works with all browser,  first place the cursor over the link, then click/ press  the middle button of the mouse.


4. Let your bookmarks bar appear: Bookmarks save a lot of time, and used frequently to access our favorite site. thus keeping the bookmark bar appear speed up things much faster.
go to settings, to change the "Appearance"

Extra tip: You can furthur customize the book mark bar for allocating much more links, by omitting the name/tittle and leaving only the icons. like this:

5. Customise google search: You can change the search setting, by clicking the gear icon on the top-right corner. If you want to open the links of the google search result unto new tab automatically, then  watch for these:

"Where results open" and check option for "Open each selected result in a new browser window."

6.Real extension of a file : One of the uses that i found very interesting is to use Google chrome for navigating files and folders in my computer. From there i can check the extension of a file.

just type file:///C:/  in the address bar.
extra tip: Just change the drive name "C", with your preferred drive name. Same came told for Mozilla firefox too.

7.Play Movies: No, not just movies(MP4) only, MP3 too and read PDFs. Just use the point 6 to locate the file. Or Drag the file and Drop into a new window of Google chrome.

8. Save a page: Saving a page is not a new thing, but often we overlook it. Thus is for reminder purpose.(ctrl + s)
