This article describes the fabrication of nanosized magneto-vesicles (MVs) comprising tunable layers densely packed superparamagnetic iron oxide nanoparticles (SPIONs) in membranes via cooperative assembly polymer-tethered SPIONs and free poly(styrene)-b-poly(acrylic acid) (PS-b-PAA). The membrane thickness MVs could be well controlled from 9.8 to 93.2 nm by varying weight ratio PS-b-PAA SPIONs. increase was accompanied transition monolayer MVs, double-layered multilayered (MuMVs). can...

Abstract Long persistent luminescence (LPL) materials of SrAl 2 O 4 doped with Eu 2+ or Dy 3+ can maintain emission over hours after ceasing the excitation but suffer from insolubility, high cost, and harsh preparation. Recently, organic LPL guest‐host exciplex systems has been demonstrated via an intermediate charge‐separated state flexible design poor air‐stability. Here, we synthesized a nontoxic two‐dimensional organic–inorganic metal hybrid halides (OIMHs), called PBA [ZnX ] X=Br Cl...
In China many respiratory pathogens stayed low activities amid the COVID-19 pandemic due to strict measures and controls. We here aimed study epidemiological clinical characteristics of pediatric inpatients with Mycoplasma pneumoniae pneumonia (MPP) after mandatory restrictions were lifted, in comparison those before pandemic. included 4,296 patients MPP, hospitalized by two medical centers Jiangsu Province, China, from January 2015 March 2024. Patients divided into pre-COVID (n = 1,662)...
The photoinduced disconnection of an oxazine heterocycle from a borondipyrromethene (BODIPY) chromophore activates bright far-red fluorescence. high brightness the product and lack autofluorescence in this spectral region allow its detection at single-molecule level within organelles live cells. Indeed, these photoactivatable fluorophores localize lysosomal compartments remain covalently immobilized organelles. suppression diffusion allows reiterative reconstruction subdiffraction images...
Self-assembling nanoparticles of amphiphilic polymers can transport hydrophobic molecules across hydrophilic media and, as a result, be valuable delivery vehicles for diversity biomedical applications. Strategies to monitor their dynamics noninvasively and in real time are, therefore, essential investigate translocation within soft matrices possibly, rationalize the mechanisms responsible diffusion biological media. In this context, we designed molecular guests with photoactivatable...
Abstract Organic fluorescence scintillators, owing to the ultrafast response time, versatile chemical structures, low processing temperature, and cost, are considered as one of promising materials for medical diagnostics, radiation detection, X‐ray astronomy. However, radioluminescence (RL) intensity sensitivity hinder their practical applications. In this work, a highly efficient organic fluorescent scintillator, 4,4′‐bis(9‐carbazolyl)biphenyl (CBP), is presented, exhibiting high RL...

We developed transmission diffraction grating-based spectroscopic single-molecule localization microscopy (sSMLM) to collect the spatial and spectral information of blinking events concurrently. characterized heterogeneities multiple far-red emitting dyes in a high-throughput manner using sSMLM. also investigated influence dispersion on identification performance fluorophores with large overlapping. The careful tuning sSMLM permitted simultaneous three-color super-resolution imaging fixed...
Abstract Spectroscopic single-molecule localization microscopy (sSMLM) was used to achieve simultaneous imaging and spectral analysis of single molecules for the first time. Current sSMLM fundamentally suffers from a reduced photon budget because photons individual stochastic emissions are divided into spatial channels. Therefore, both only use portion total photons, leading precisions in To improve precisions, we present symmetrically dispersed sSMLM, or SDsSMLM, fully utilize all SDsSMLM...

Here, we report a novel porous framework system based on macrocyclic trimers assembled from open‐shell tetraarylethylene building blocks with aryldicyanomethyl radicals as coupling linkers. Under mechanical, thermal, or chemical stimuli, the showed adaptability by activating conformational dynamics radical‐based transformations, thus displaying macroscopic...

A photochemical strategy to encode fluorescence signals in vivo with spatial control was designed around the unique properties of a photoactivatable borondipyrromethene (BODIPY). The photoinduced disconnection two oxazines, flanking single BODIPY, consecutive steps produces mixture three emissive molecules resolved inside polymer beads. relative amounts and emission intensities fluorophores can be regulated precisely each bead by adjusting dose activating photons mark individual particles...
Spectroscopic single-molecule localization microscopy (sSMLM) captures the full emission spectra of individual molecules while simultaneously localizing their spatial locations at a precision greatly exceeding optical diffraction limit. To achieve this, sSMLM uses dispersive component to separate emitted photons into dedicated and spectral imaging channels for simultaneous acquisition. While adding cylindrical lens in channel enabled three-dimensional (3D) sSMLM, inherent astigmatism leads...
Spectroscopic single-molecule localization microscopy (sSMLM) simultaneously provides spatial and spectral information of individual single-molecules emission, offering multicolor super-resolution imaging multiple molecules in a single sample with the nanoscopic resolution. However, this technique is limited by requirements acquiring large number frames to reconstruct image. In addition, sSMLM suffers from cross-talk while using dyes relatively broad bands that produce cross-color...
