A new technique has been developed to precisely detect diseases from DNA samples. This paper-based technique allows the results to be seen with naked eyes, similar to a pregnancy test. Here, the paper strip is dipped into a processed sample where a line appears on the paper, indicating whether the target molecule was detected or not.
This technique is based on the version SHERLOCK (Specific High Sensitivity Reporter unLOCKing). According to the MIT professor , “SHERLOCK provides an inexpensive, easy-to-use, and sensitive diagnostic method for detecting nucleic acid material - and that can mean a virus, tumor DNA, and many other targets” SHERLOCK was used to detect cell-free tumor DNA in blood samples from patients with lung cancer and detect synthetic Zika and Dengue virus simultaneously. This new paper readout technique for SHERLOCK tells whether the target is present in the sample,…
