High-impact diseases, including cancer, cardiovascular disease, and neurological disease, are challenging to diagnose without supplementing clinical evaluation with laboratory testing. Even with laboratory tools, definitive diagnosis often remains elusive. The lack of three crucial elements presents a road block to achieving the potential of clinical diagnostic tests: (1) definitive disease-associated protein and genetic markers, (2) easy and inexpensive sampling methods with minimal discomfort for the subject, and (3) an accurate and quantitative diagnostic platform. Our aim is to develop and validate a solution for requirement (3) and also to develop a portable system. Requirements (1) and (2) will be addressed through the utilization of novel and highly specific oral cancer saliva proteomic and genomic biomarkers and the use of saliva as the biofluid of choice, respectively. The Oral Fluid NanoSensor Test (OFNASET) technology platform combines cutting-edge technologies, such as self-assembled monolayers (SAM), bionanotechnology, cyclic enzymatic amplification, and microfluidics, with several well-established techniques including microinjection molding, hybridization-based detection, and molecular purification. The intended use of the OFNASET is for the point of care multiplex detection of salivary biomarkers for oral cancer. We have demonstrated that the combination of two salivary proteomic biomarkers (thioredoxin and IL-8) and four salivary mRNA biomarkers (SAT, ODZ, IL-8, and IL-1b) can detect oral cancer with high specificity and sensitivity. Our preliminary studies have shown compelling results. We sequentially delivered a serial dilution of IL-8 antigen, probe solution, wash, enzyme solution, wash, and mediator solution to sensor reaction chambers housed in a prototype cartridge and demonstrated strong signal separation at 50 pg/mL above a negative control.
