Title: Development of a Nanoprobe-biosensing approach for direct early-phase detection of cancer cells

Abstract:

An appropriate detection method for simple and rapid differentiation of cancercells at early stages is of high demand. Nanobiosensingapproaches based on developing specific probes could provide ideal molecular detection method for cells and pathogens. Currently, the new approach in developing diagnostic tests is to replace conventional methods with molecular lab-on-a-chip procedures with high sensitivity and point-of-care testing. In that regard, nucleic acid testing (NAT) is of great focus because of high specificity and sensitivity. We have developed a novel detection technique based on noncoding RNA and gold nanoprobeswithboth improved targeting and detection strategies for nanodiagnosis of the most prevalent cancer cells including breast, colon, lung, prostate, pancreas, gastric, and liver. The nanoprobe-biosensingmethod was also improved to remove amplification stage and lower the overall assay time. The limit of detection (LOD) of this method was determined as2 ng/µl RNA in isolated solution which was detectable by naked eye. Results show that the proposed method could be used as a simple, rapid, sensitive platform for diagnosis of cancers before their physiological symptoms appear. This could be a promising evolution in increase the patients’ survival rate.
