It is common knowledge that when it comes to any disease, the key to treatment is early detection. While this isn’t a big problem for people in big cities, it’s still a hassle for those who live in rural areas.
The problem being not only the lack of testing centers, but also the fact that most testing centers in remote areas aren’t equipped for extensive testing.
The only solution remains sending blood samples to other labs far away that actually have the capability to carry our said extensive testing.
However, this process not only takes a lot of time and energy, but is also quite expensive. To provide an alternate solution to this problem, researchers at Ohio State University have developed disposable paper strips for disease detection.
Just like other home tests, you just place a drop of blood of paper on the strip, which then seals and secures it. This strip can then be sent to labs for proper testing.
The strips in question are made from sheets of white paper, stuck together with adhesive tape. This setup is then run through an inkjet printer and covered in wax ink in order to create special locations for securing your blood sample.
Since the storage requirements are so minimal, these strips are as small as a regular postage stamp, so you can easily transport them via regular mail.
This not only makes it a cheap alternative to regular options, but also keeps the sample protected against light, temperature and humidity.
The shelf life of these samples is upto 30 days, which makes sure that you don’t have to worry about your samples getting corrupted on long journeys.
If all these benefits of this technology weren’t enough, the researchers have also made sure that these strips are cheap as well, with one only costing about 50 cents.
The researchers will now work on trying to make these strips more sensitive as well as more cheaper, so that they can be used to provide life saving diagnosis for a host of serious diseases such as malaria and cancer among others.
