This review article deals with the concepts, principles and applications of visible-light and
near-infrared (NIR) fluorescence and surface-enhanced Raman scattering (SERS) in in vitro …

Catalytic hairpin assembly (CHA) with advantages of high efficiency, flexible design, and
mild reaction condition is considered a promising molecular amplifier. Modified working …

Cancer-cell-derived exosomes are regarded as noninvasive biomarkers for early cancer
diagnosis because of their critical roles in intercellular communication and molecular …

Catalytic hairpin assembly (CHA) has previously proven useful as a transduction and
amplification method for nucleic acid detection. However, the two hairpin substrates in a …

Metastasis attributed to approximately 90% of cancer-related deaths; hence, the detection of
metastatic tumor–derived components in the blood assists in determining cancer recurrence …

MicroRNAs (miRNAs) are small non-coding RNAs that regulate important physiological
processes, and their dysregulation is associated with various human diseases …

Biomolecular receptors such as nucleic acids that switch between two or more
conformations upon binding to a specific target can be used to build specific and sensitive …

A sensitive nucleic acid detection platform based on superhydrophilic microwells spotted on
a superhydrophobic substrate is fabricated. Due to the wettability differences, ultratrace DNA …

In this work, a simple and label-free electrochemical biosensor is developed for microRNA
(miRNA) detection on the basis of an arched probe mediated isothermal exponential …

In this work, on the basis of a new 2D DNA nanoprobe (DNP) and an enzyme-free-target-
recycling amplification, an electrochemical biosensor is developed for the ultrasensitive …
