Abstract Titanium nitride (TiN), as an excellent alternative plasmonic supporting material compared to gold and silver, exhibits tunable properties in the visible near‐infrared spectra. However, label‐free surface plasmon resonance biosensing with TiN is seldom reported due lack of proper functionalization protocols. Herein, this study reports biotinylated antibody‐functionalized (BAF‐TiN) for high‐performance applications. The BAF‐TiN biosensor can quantitatively detect exosomes 30–200 nm...
Noninvasive detection of exosomal MCT1/CD147 can monitor the progression glioma, a fatal brain tumor, as liquid biopsy.
Surface modification by metal doping is an effective treatment technique for improving surface properties CO2 reduction. Herein, the effects of doped Pd, Ru, and Cu on adsorption, activation, reduction selectivity CeO2(111) were investigated periodic density functional theory. The metals distorted configuration a perfect weakening adjacent Ce–O bond strength, Pd was beneficial generating highly active O vacancy. analyses adsorption energy, charge difference, states confirmed that conducive...
PtSn alloy, which is a potential material for use in direct methanol fuel cells, can efficiently promote oxidation and alleviate the CO poisoning problem. Herein, decomposition on Pt3Sn(111) was systematically investigated using periodic density functional theory microkinetic modeling. The geometries energies of all involved species were analyzed, network mapped out to elaborate reaction mechanisms. Our results indicated that formaldehyde weakly adsorbed, other derivatives (CHxOHy, x = 1–3,...
A novel differential phase detecting surface plasmon resonance (SPR) sensor based on white-light spectral interferometry is presented. Our proposed scheme employs a source for SPR excitation and measures the corresponding change at optimized coupling wavelength with fixed angle of incidence across visible spectrum. Compared to existing laser schemes, this system offers optimal sensitivity extended dynamic range measurement without any compromise in detection resolution. Results obtained from...
A highly efficient and pH-universal hydrogen evolution reaction (HER) electrocatalyst with a sandwich-architecture constructed using zero-dimensional N- P-dual-doped core-shell Co2 P@C nanoparticles embedded into 3 D porous carbon sandwich (Co2 P@N,P-C/CG) was synthesized through facile two-step hydrothermal carbonization pyrolysis method. The interfacial electron transfer rate the number of active sites increased owing to synergistic effect between N,P-dual-doped sandwich-nanostructured...
To reduce costs and facilitate automation in the automotive industry, adhesive bonding has gained popularity as a replacement for conventional mechanical fasteners such bolts, screws, rivets, welding. Adhesive is particularly useful parts made of plastics polymer composites, which are playing an increasing role reducing vehicle weight. However, process more susceptible to quality variations during manufacturing than traditional joining fastening methods. Shearography pulsed thermography...
Incorporating the temporal carrier technique with common-path spectral interferometry, we have successfully demonstrated an advanced surface plasmon resonance (SPR) biosensing system which achieves refractive index resolution (RIR) up to 2 × 10(-8) unit (RIU) over a wide dynamic range of 3 10(-2) RIU. While this is accomplished by optimizing SPR differential phase sensing conditions just layer gold, managed address discontinuity novel spectral-temporal measurement scheme. As new optical...
