Despite their high analytical performance, conventional analytical biosensor devices are
usually difficult to handle, time-consuming, bulky and expensive. As a result, their …

For the past decades, several cancer biomarkers have been exploited for rapid and accurate
prognosis or diagnosis purposes. In this review, the optical biosensor is targeted for …

Both programmed death-1 (PD-1) and programmed death-ligand 1 (PD-L1) are important
proteins in cancer immunotherapy. Soluble forms (sPD-1 and sPD-L1) have potential for …

Enhancing the sensitivity of photoelectrochemical (PEC) assays poses a challenging task.
This study proposes a method to improve the sensitivity of PEC assays by creating a three …

Constructing of heterostructures can significantly improve the photoelectrical (PEC)
response signal by promoting the migration and suppressing the recombination of …

Herein, a facile fluorescent CRISPR-Cas12a-based sensing strategy is presented for
prostate specific antigen (PSA), as a prostate cancer biomarker, with the assistance of a …

Early detection of cancers is key to a better prognosis. Advanced proteomics and genomic
detection techniques offer great specificity and sensitivity, however, delayed symptomatic …

In consideration of the problems related to food safety, environmental pollution, and the
spread of infected diseases nowadays, we urgently need testing methods that can be easily …

Current molecular logic gates are predominantly focused on the qualitative assessment of
target presence, which has certain limitations in scenarios requiring quantitative …

A typical colorimetric sandwich-type sensor relies on dual antibodies/aptamers to
specifically visualize the targets. The requirement of dual antibodies/aptamers and low …
