Numerous studies have determined that physical cues, especially the nanotopography of materials, play key roles in directing stem cell differentiation. However, most research on nanoarrays for fate regulation is based nonbiodegradable such as silicon wafers, TiO2, and poly(methyl methacrylate), which are rarely used tissue engineering biomaterials. In this study, we prepared biodegradable polylactic acid (PLA) nanopillar arrays with different diameters but same center-to-center distance...
Localized surface plasmon resonance-based plasmonic biosensors are interesting candidates for the design of portable optical biosensor platforms owing to their integration, miniaturization, multiparameter, real-time, and label-free detection characteristics. Plasmonic arrays that have been combined with microfluidics developed herein detect exosomes label-free. Gold nano-ellipsoid were fabricated low-cost anodic aluminum oxide thin films act as shadow masks evaporation Au. The integrated a...
It is well-accepted that most osteogenic differentiation processes do need growth factors assistance to improve efficiency. As a material cue, hydroxyapatite (HAp) can promote of stem cells only in way. Up now, rare work related the relationship between HAp nanostructures and process without has been reported. In this study, one-dimensional (1D) with tunable length were synthesized by an oleic acid assisted solvothermal method adjusting alcohol/water ratio (η). The morphology 1D be changed...
Carbon quantum dots (CQDs) are a new type of fluorescent nanoparticle for cell imaging and tracking. However, they would easily diffuse quench, followed by the loss their fluorescence ability. By connecting functional groups with other nanoparticles, CQDs will be protected from destruction exhibit long-time fluorescence. Here, carbon dot–hydroxyapatite (CQD–HAp) hybrid nanorods were prepared self-assembly on surface HAp through facile one-pot process. The morphology size CQD–HAp can well...
Detecting biomarkers is an efficient method to diagnose and monitor patients' stages. For more accurate diagnoses, continuously detecting monitoring multiple are needed. To achieve point-of-care testing (POCT) of biomarkers, a smartphone biosensor system with the multi-testing-unit (SBSM) based on localized surface plasmon resonance (LSPR) integrated multi-channel microfluidics was presented. The SBSM could simultaneously record nine sensor units detection biomarkers. Additional 72 were...
Surface plasmons of metal nanostructures can resonantly enhance the light absorption two-dimensional (2D) materials and stacked van der Waals (vdW) heterostructure-based photodetectors, realizing improvement responsivity. So far, it has remained challenging to control tune surface via artificially varying geometry arrayed nanostructures. Here, we demonstrate a broadband plasmonic photodetector based on an integration gold nanoparticles (Au NPs) WSe2/MoS2 vdW heterostructure. The plasmon...
Terbium–aspartic acid (Tb–Asp) nanocrystals with chirality-dependent tunable fluorescent properties can be synthesized through a facile synthesis method the coordination between Tb and Asp. Asp different chirality (dextrorotation/d levogyration/l) changes stability of center following absorption/emission ability differences. Compared l-Asp, d-Asp coordinate to form more stable center, higher quantum yield longer fluorescence life. Fluorescence intensity Tb–Asp linearly increases increase...

Biosensors based on Rayleigh anomaly (RA) in metal gratings exhibit impressive bulk refractive index (RI) sensitivity and narrow linewidth. However, the electric field enhancement extends far away from surface of gratings, which limits application biosensor where RI changes are restricted at sensor interface. To overcome this shortcoming, a novel grating composed 8-layer Au/Al2O3 stack was optimized by numerical simulation. The is limited several hundreds nanometers surface. increases 10...
