Paper Microscope for less than a dollar?
Stanford scientists have developed a paper microscope called FoldScope that, unbelievably, costs less than a buck.
The main motive behind the creation of the microscope was the fight against malaria. In developing countries, about a billion microscopic examination of blood samples should be carried out per year for malaria diagnosis.
Paper microscope fits in your pocket, weighs less than ten grams, can be used for bright-field, dark-field, polarization and fluorescence microscopy, and even work as a projector. One battery lasts for 50 hours. Paper Microscope can endure any rough treatment, it can be dropped on the floor – it can withstand anything that a piece of cardboard can. Microscope image quality is sufficient enough to determine different types of infections in the field.A short training lesson will be enough for a student to learn how to make a paper microscope and conduct series of experiments.

Re: Paper Microscope for less than a dollar?
I think my local Dollar Store has some microscopes for a buck, too. Bet these ones don't come with Dora the Explorer on the side, nor do they come in 3 bright, enticing colors.

The main,main motive though was to obtain research grants with a side order of a bit of fame.

Also, if so many of the same thing needs to be performed, perhaps the Billion dollars ($1 per unit, right) might be better placed in durable, reusable equipment. I don't see any of the modern manufacturing facilities developing a throwaway paper wrench. :idunno:
Re: Paper Microscope for less than a dollar?
It amazes me that they can spend $millions on developing a paper microscope to combat malaria, when it would be more prudent to spend $millions on combating malaria directly.
It reminds me of the UK Government who spend more on advertising about benefit fraud than they lose to benefit fraud, meaning that they spend more than they save.
What next? Paper cars? (Trabant, anyone).

Diagnosis is a key component, for what good are cures if you can't identify the sick?
You make a valid point, except that I cannot remember the last time my doctor got his microscope out to diagnose my illness.
Mind you, if you are referring to blood analysis, then you would need to examine it under a paper microscope, once you have extracted it using a paper syringe, connected to a paper needle (disposable, as you wouldn't want to contaminate those further down the line with a re-usable paper needle).

You'd be lucky to have a doctor listen to 10 of the words that came out of your mouth let alone do lab work.
Also, go get yourself some of that malaria. Then, follow your blood trail to a microscope that prices in the range of $500-$1500.
Then I must be a lucky guy. I also drink plenty of Tonic Water, liberally spiced with Gin, so the chances of catching Malaria are slim (not counting that I don't live near swamp land anyway).
Microscopes are ten a penny these days. You can pick them up for less than £10 new, and second hand ones even cheaper. Since microscopes have been around for 500 years or more, I should imagine that there are large stocks of refurbished microscopes just waiting for a new home.
The Documators we used to use to inspect contact lenses were all second hand and cost less than $50 each. Some required recalibration but they all worked fine.
A paper microscope can still be affected by moisture in the air, which could cause degradation, whereas one made from metal or plastic will be much more durable, and last longer than the person using it.

Its size is small. Its value is same.
