Turning a Smart Phone Into a Microscope 43
MTorrice writes "By attaching a lightweight, inexpensive device to the back of a smart phone, scientists can convert the phone into a sensitive fluorescence microscope. The attachment [paper abstract] allows the phone's camera to take pictures of single nanoparticles and viruses, possibly providing a portable diagnostic tool for health care workers in developing countries. For example, doctors in remote regions could use the technique to measure HIV viral loads in patients' blood samples, allowing the doctors to easily monitor disease progression and determine the best course of treatment."

one of the smallest things in a microscope is the lens. most of the microscope is precision, vibration damped, gearing to manipulate the focal distance precisely. If you are going for high resolution its not yet clear to me how you avoid the expensive non-portable part of the microscope.
Don't forget, this isn't talking about a standard "microscope" but rather a "fluorescence microscope", which is actually a fairly different thing.
The linked article (and linked paper abstract) has images that give you an idea of what they're doing much better than TFA does.

These diagnostic patents are all held and defended by the American drug company cartels who hold the world ransom. Same thing applies to the detection of the breast cancer gene, that is why you only see the wealthy being tested for this indicator gene, then deciding to have their breasts removed if they inherited the gene. Nothing is holding back the rapid advancement of diagnostics more than the drug company cartels and they need to be broken up permanently the same way standard oil was dealt with!
All well and good developing cheap portable diagnostic devices but if ideas like, doing assay by the software counting a specific shape can be individually patented per shape and are then held ransom by crooked corporations with cooked up patents these devices will be far too expensive to do any good at all.
