Dual polarity MALDI imaging mass spectrometry on the same pixel points reveals spatial lipid localizations at high-spatial resolutions in rat small intestine
Sensitive laser desorption/ionization obtained via a sublimation-coated 1,5 diaminonaphthalene (1,5-DAN) matrix allowed dual polarity MALDI-IMS analysis on the same pixel points across the jejunal mucosa.
A Ni3N–Co3N hybrid nanowire array electrode for high-performance nonenzymatic glucose detection
In this communication, we report a new type of nickel cobalt nitride hybrid nanowire array in situ grown on a Ti plate (Ni3N–Co3N NW/Ti) topotactically converted from Ni–Co hydroxide as a high-active catalyst electrode for glucose electrooxidation in alkaline media.
A pilot study in humans of microneedle sensor arrays for continuous glucose monitoring
Although subcutaneously implanted continuous glucose monitoring (CGM) devices have been shown to support diabetes self-management, their uptake remains low due to high costs and poor accuracy and precision arising from their invasiveness.
Paper
Measuring the size and density of nanoparticles by centrifugal sedimentation and flotation
Analytical centrifugation in sedimentation and flotation modes is used to measure both the size and density of polystyrene nanoparticles.
Paper
Determination of amphetamine-type stimulants (ATSs) and synthetic cathinones in urine using solid phase micro-extraction fibre tips and gas chromatography-mass spectrometry
An optimum condition procedure applied to a SPME PDMS/DVB fiber tip in a mixture of drugs in a urine sample.
Paper
Raman spectroscopic library of medieval pigments collected with five different wavelengths for investigation of illuminated manuscripts
Stepwise identification of medieval pigments by Raman spectra data and excitation source.
An electrochemiluminescence sensor based on CdSe@CdS functionalized MoS2 and hemin/G-quadruplex-based DNAzyme biocatalytic precipitation for sensitive detection of Pb(II)
A novel electrochemiluminescence biosensor based on CdSe@CdS quantum dots functionalized MoS2 modified electrode was developed for sensitive detection of Pb(II) using HRP-mimicking DNAzyme biocatalytic reaction.
