Ultrasensitive electrochemical detection of miRNA based on DNA strand displacement polymerization and Ca2+-dependent DNAzyme cleavage
An ultrasensitive electrochemical sensing strategy for the detection of miRNA is developed combining strand displacement polymerization and a DNAzyme-catalyzed cleavage reaction.
A thumb-size electrochemical system for portable sensors
A thumb-size and precise electrochemical system is designed for sensors in size and cost sensitive applications.
Filter paper based SERS substrate for the direct detection of analytes in complex matrices
Spray coating paper with plasmonic aggregates/hydroxyethylcellulose solution allows fabrication of cheap SERS active substrates for direct analysis of protein/mud samples.
Affinity-free enrichment and mass spectrometry analysis of the ovarian cancer biomarker CA125 (MUC16) from patient-derived ascites
Developing a mass spectrometry-based assay for the ovarian cancer biomarker CA125 (MUC16) is a desirable goal, because it may enable detection of proteoforms that are analytically silent in the current immunoassay.

Zero electrical power pump for portable high-performance liquid chromatography
A major trend in analytical chemistry is the miniaturization of laboratory instrumentation. We present a portable high-performance liquid chromatography system for field based chemical analyses.
CIRDES: an efficient genome-wide method for in vivo RNA–RNA interactome analysis
Complex RNA–RNA interactions underlie fundamental biological processes.
Ultrasensitive detection of lung cancer-associated miRNAs by multiple primer-mediated rolling circle amplification coupled with a graphene oxide fluorescence-based (MPRCA-GO) sensor
MPRCA-GO sensor can detect low amount of miRNAs, which are biomarkers in cancer diagnosis.
Subsecond detection of guanosine using fast-scan cyclic voltammetry
We present the first electrochemical characterization of guanosine, a purinergic neuromodulator and neuroprotector, using fast-scan cyclic voltammetry at carbon-fiber microelectrodes.
