In this work we explore the effects of wild-type and single nucleotide polymorphism (SNP) target specie concentrations, temperature, and the time of hybridization on sensing specificity in two component systems. A finite element method is used to simulate the diffusion of DNA through a microfluidic chamber to the sensing surface of bound oligonucleotide probes where hybridization of DNA is modeled using the corresponding chemical reaction equation assuming low grafting density.
When there is a need to quickly analyze samples using a number of different PCR assays, it is likely that optimal conditions for each assay will not be the same. First, different assays often will require different annealing temperatures for their primers. In addition, amplicons may be designed to be of different lengths and therefore require varying durations of the extension step.READ MORE
