Ultrasensitive detection of microRNA-21 based on electrophoresis assisted cascade chemiluminescence signal amplification for the identification of cancer cells
The accurate detection of allergen specific IgE (sIgE) is fundamental in the diagnosis of allergic disease. The present commercial platforms fail to meet the need for personalized diagnosis, due to...
lncRNA biosensor based on single-wall carbon nanotubes wrapped with Au–Rh hollow nanospheres (Au/Rh-HNP@SWCNT) complex signal amplification and an l-Cys Au nano-film provided ultrasensitive detection for the nuclear paraspeckle assembly transcript 1 (NEAT1).
In this communication, we proposed a new enzyme-free quadratic SERS signal amplification approach for the ultrasensitive detection of circulating miRNA in human serum.
A reusable aptasensor based on the dual signal amplification of Ce@AuNRs-PAMAM-Fc and DNA walker for ultrasensitive detection of TNF-α
