Development of a selective-iodide indicator for live-cell imaging and evaluation of CFTR activity
I-Sense is taken up by the cell and exhibits decreased fluorescence in the presence of iodide, serving as an intercellular iodide indicator for monitoring CFTR activity.
Paper
Reversible dual-mode detection of Cu2+ and tandem capture of cysteine using a salphen-conjugated microporous polymer
A salphen-conjugated microporous polymer shows both fluorescence and colorimetric changes to nanomolar Cu2+ and is used for tandem detection of cysteine.
Paper
A digital nonenzymatic nucleic acid amplification assay for ultrasensitive detection of cell-free microRNA in human serum
A digital, multi-layer nonenzymatic nucleic acid amplification assay (SENA) was developed for quantifying miRNA expression levels in diluted human serum samples.
Paper
Deciphering target-binding selectivity of waste printed circuit board-derived carbon nanozymes for pyrophosphate sensing
WPCB-derived carbon nanozymes exhibit selective catalytic inhibition in response to pyrophosphate, enabling sensitive colorimetric detection without external recognition elements.
Paper
A near-infrared fluorescent aptananosensor enables selective detection of the stress hormone cortisol in artificial cerebrospinal fluid
In this study, we used carbon nanotubes and a ssDNA aptamer to design a fluorescent sensor to detect cortisol, which we showed we could do in a selective manner compared to estradiol and could do in artificial cerebrospinal fluid.
Paper
High-wavenumber Raman spectroscopy for the detection of Mycobacterium tuberculosis in saliva
High-wavenumber Raman spectroscopy enables reagent-free optical detection of Mycobacterium tuberculosis in human saliva samples at a physiologically-relevant concentration.
