Abstract The manipulation of cell identity by reprograming holds immense potential in regenerative medicine, but is often limited the inefficient acquisition fully functional cells. This problem can potentially be resolved better understanding reprogramming process using vivo genetic models, which are currently scarce. Here we report that both enterocytes (ECs) and enteroendocrine cells (EEs) adult Drosophila midgut show a surprising degree plasticity. Depleting transcription factor...
Label-free single-nanoparticle detection is crucial for the fast of nanoparticles and viruses in environmental monitoring biological sciences. In this Letter, benefiting from leakage radiation that transforms near-field surface plasmon polariton (SPP) distribution along interface to far field, we demonstrated plasmonic imaging single polystyrene with a particle size down 39 nm. The composed localized enhancement interference SPPs. result accumulation charges around nanoparticle, it connected...
Directionally scattered surface plasmon polaritons (SPPs) promote the efficiency of plasmonic devices by limiting energy within a given spatial domain, which is one key issues to devices. Benefitting from magnetic response induced in high-index dielectric nanoparticles, unidirectionally SPPs have been achieved via interference between electric and resonances excited particles. Yet, as low-index nanoparticles too weak, directionally are hard detect. In this work, we demonstrate forward single...
The rabbit is considered an important model animal from which to obtain embryonic stem cells because of the utility this in physiology and reproductive research. Here, we derived ES-like (rES-like) blastocysts superovulated Japanese white rabbits using culture medium containing 10-7 M melatonin, 10 ng/mL basic fibroblast growth factor, 1,000 IU/mL human leukemia inhibitory factor. This concentration melatonin had most significant positive effects on proliferation inner cell mass-derived...
Due to their excellent physical and chemical properties, graphene sheets are widely used in industry, which makes detection important guarantee performance. Atomic force microscopy, scanning electron Raman spectroscopy the most common methods, is either time-consuming or easily destructive. In this work, we presented a fast nondestructive method detect single by using plasmonic imaging. Dual channel sampling imaging combining image processing algorithm improve deterioration from propagation...
Plasmonic interferometric imaging has been widely used for fast and label-free detection to nano-objects, which associates the interference between launched scattered surface plasmon polaritons (SPPs). As scattering of SPPs is affected by characteristics particle size, index particle-interface distances have retrieved from imaging. Refractive dielectric, tailors resonant wavelength SPPs, also a key issue plasmonic Yet, influence refractive not investigated. In this work, we connected...
Label-free, fast, and single nanoparticle detection is demanded for the in situ monitoring of nano-pollutants environment, which have potential toxic effects on human health. We present label-free imaging nanoparticles by using total internal reflection (TIR)-based leakage radiation microscopy. illustrate both polystyrene (PS) Au nanospheres with diameters as low 100 30 nm, respectively. As far-field simulated near-field electric field intensity distribution at interface showed same...
The directional scattering in low-index dielectric nanoparticles is hard to detect, as the multipole resonances are weak. With surface plasmon polariton (SPP) induced moments, we observed SPP by single polystyrene nanoparticles.
We presented a method to manipulate the surface plasmon propagation by using total reflection of single hollow nanoparticle. used plasmonic imaging observe manipulation nanoparticle in different surrounding medium.
