As a kind of excellent biomaterials, deoxyribonucleic acids (DNAs) have been employed to
build a variety of biosensors via the interactions between DNAs and biomolecules or …

Large differences between the DPP responses of ss-and dsDNAs (Figure 4B) suggest that
the double-helical structure of the dsDNA is not significantly disturbed at the DME surface …

As an important biomarker for early cancer diagnostics and a valuable therapeutic target,
telomerase has attracted extensive attention concerning its detection and monitoring …

Here, an ultrasensitive “off–on” electrochemiluminescence (ECL) biosensor was proposed
for the determination of telomerase activity by using a self-enhanced ruthenium …

Human telomerase is a ribonucleoprotein that adds the TTAGGG repeats on the telomeric
ends of chromosomal DNA, it protects chromosomes from fusion, recombination and …

We report an electrochemical sensor for telomerase activity detection based on spherical
nucleic acids gold nanoparticles (SNAs AuNPs) triggered mimic-hybridization chain reaction …

Human telomerase is a ribonucleoprotein complex that functions as a telomere terminal
transferase by adding multiple TTAGGG hexamer repeats using its integral RNA as the …

We report a new assay for human telomerase activity that relies on polyvalent
oligonucleotide nanoparticle conjugates as diagnostic probes and amplification units. Gold …

Telomerase, a valuable biomarker, is highly correlated with the development of most of
human cancers. Here, we develop a bidirectional strategy for telomerase activity detection …

This work reports on a simple and sensitive electrochemical strategy for the detection of
telomerase extracted from HeLa cells. It was based on the signal amplification of in-situ …
