When I typed microscope in google, I found the following advertisement from eBay India.
From that we get the idea that microscope cost in India varies in the range: ₹1,500-7,000, which may not sound too cheap to be provided all health centers for diagnostic requirements in India or many other countries. Now Manu Prakash, who is presently an assistant professor in the Bioengineering Dept. of Stanford University (an IIT Kanpur alumni as well), came up with an innovative invention: the Foldscope. It’s a microscope obtained just by folding papers in a way that a 2.4mm ball lens can be mounted by using the capillary-encapsulation technology. Manu claimed that the whole fabrication costs around 50 cents which will be below ₹50 in Indian market. Watch out this brilliant TED show.
Could you ever imagine it? He called it a use-and-through microscope! The invention sounds like a revolution!
