Label-free quantification methods for nucleic acids are attracting attention, since they provide potential tools in clinical applications such as disease diagnosis or prognosis observation. In this research, we developed a simpler and cost-effective electrical monitoring device of nucleic acid amplification, combining an isothermal amplification method and an Iridium/Iridium oxide (Ir/IrOx) electrode...
This work describes a label free, potentiometric method to detect cell surface sialic acid (SA) using phenylboronic acid (PBA) compound integrated into the form of self-assembled monolayer (SAM) on a field effect transistor (FET) extended gold gate electrode. Due to predominant binding between undisassociated PBA and SA at pH 7.4, we found that carboxyl anions of SA were exclusively detectable among...
