The field of aptamer-based sensing has evolved considerably over the past three decades.
The aptamer sensor-based detection of small-molecule targets in body fluids is designed for …

Sensors employing split aptamers that reassemble in the presence of a target can achieve
excellent specificity, but the accompanying reduction of target affinity mitigates any overall …

Up to now, many different methods have been developed for detection of cocaine, but most
of these methods are usually time-consuming, tedious and require special or expensive …

This paper describes a label-free and real-time piezoelectric aptasensor for the detection of
cocaine. The acoustic wave sensing platform is a quartz substrate functionalized with an …

Cocaine is one of the most used illegal recreational drugs. Developing an on-site test for
cocaine use detection has been a focus of research effort, since it is essential to the control …

Screen printed carbon nanotube electrodes (SPEs) are explored as electroanalytical
sensing platforms for the detection of capsaicin in both synthetic capsaicin solutions and …

An aptamer-based assay is described for the determination of trace levels of the cancer
marker human epidermal growth factor receptor-2 (HER2) and living MCF-7 cells. The …
