Upconversion emission enhancement mechanisms of Nd<sup>3+</sup> sensitized NaYF<sub>4</sub>:Yb<sup>3+</sup>,Er<sup>3+</sup> nanoparticles was obtained by using tunable plasmonic Au films.
Abstract Outbreaks of infectious viruses offer a formidable challenge to public healthcare systems and early detection is essential for preventing virus propagation. In this work, an ultrasensitive plasmon‐enhanced fluorescence resonance energy transfer (FRET) biosensor based on core‐shell upconversion nanoparticle (csUCNP) gold (AuNP) accurate SARS‐CoV‐2 viral RNA presented. biodetection assay, the Tm 3+ /Er co‐doped csUCNP NaGdF 4 :Yb/Tm@NaYF :Yb/Er acts as donor AuNP serves acceptor. The...
Multiplexed detection is essential in biomedical sciences since it more efficient and accurate than single-analyte detection. For an early diagnosis of COVID-19, a multiplexed strategy required to avoid false negatives with the existing gold standard assay. Nb2CTx nanosheets were found efficiently quench fluorescence emission lanthanide-doped upconversion luminescence nanoparticles at wavelengths ranging from visible near-infrared spectrum. Using this broad-spectrum quencher, we developed...

Abstract Spectral conversion technology based on NaYF 4 :Yb 3+ , Er upconversion nanoparticles was extensively used to improve photovoltaic efficiency of solar cells. However, the response mismatch between absorption semiconductors and luminescence (UCL) limits application spectral technology. Nonstoichiometric WO 2.72 display broad from visible near‐infrared region due presence oxygen vacancy, which is overlapped with UCL nanoparticles. Thus, combination nanoparticles, nonstoichiometric...
Abstract Persistent luminescence nanomaterials can remain when the light source is turned off, which exhibits promise in biosensor and bioimaging fields since they have ability to completely eradicate tissue autofluorescence. Although significant progress has been made persistent biosensing, there still a dearth of long-afterglow detection platform with low limit (LOD) high sensitivity. Herein, Zn 2 GeO 4 :Mn, Cr persistently luminescent nanorods (PLNRs) superior long afterglow time were...
Schiff-base covalent organic frameworks (COFs), recognized for their designable structures, abundant modification sites, and robust stability, are considered ideal platforms constructing biomimetic enzymes.
