The cell viabilities were measured by the standard MTT assay.F or the assessment of the photothermal effect, the procedure was identical to that of the cytotoxicity assessment, except that the samples were subjected to 808 nm NIR irradiation (1.5 Wcm À2 ,6 min per well) before adding MTT to the cell media. In addition, live/dead cell staining was performed to further evaluate the anticancer efficiency of the UCNP-Bi 2 Se 3 nanohybrid in cells, for which the calcein AM/PI costaining method was adopted.…”

Non-invasive theranosticst hat integrate the advantages of multimodality imaging and therapeuticsh ave great potentiali nt he field of biomedicine. Herein, an ew nanohybrid based on Bi 2 Se 3 -conjugated upconversion nanoparticles (UCNPs) has been successfullyd eveloped through a simple in situ growth strategy. Under 808 nm near-infrared laser irradiation, the UCNPs can emit bright visible light, whereas the Bi 2 Se 3 nanomaterial exhibits efficient photothermal conversion capacity.M oreover, the as-synthesized UCNP-Bi 2 Se 3 nanohybride xhibits efficient cell upconversion luminescence (UCL), reasonable CT imaging,a nd admirable cancerc ell ablation capacity,f urthere mphasizing the efficiencyo ft his strategy for simultaneous UCL imaging and photothermalt herapy.T he designed theranostic strategy guidedb yd ual-modali maginge ndowed with real-time dynamicm onitoring, remote controllability,a nd non-invasiveness makes the UCNP-Bi 2 Se 3 nanohybrid an ideal candidate for non-invasive multimodali maging-guided photothermal therapy for the precise diagnosis and treatment of cancer.Supporting information and the ORCID identification number(s) for the author(s) of this article can be found under: https://doi.

Dual plasmonic Au@Cu S core-shell nanorods (NRs) have been fabricated by using a hydrothermal method and plasmon-coupled effect between the Au core and Cu S shell in the near-infrared (NIR) region. The extinction spectrum of Au@Cu S NRs is dominated by the surface plasmon resonance (SPR) of the Cu S shell, the transverse surface plasmon resonance (TSPR), and the longitudinal surface plasmon resonance (LSPR) of the Au NRs. With the Cu S shell increasing (fixed Au NRs), the TSPR peak slightly redshifts and the LSPR and SPR peaks blueshift, owing to competition between the redshift of the refractive index effect and blueshift from the plasmon coupled effect. Although, for Au@Cu S NRs, only TSPR and LSPR peaks can be seen and a redshift arises with the increasing Cu S shell thickness, implying that no plasmonic coupling between Au NRs and Cu S shell occurred. The extinction spectrum of the Au@Cu S NRs with three coupled resonance peaks is simulated by using the FDTD method, taking into account the electron-transfer effect. The dispersion properties of the coupling of Au@Cu S NRs with the LSPR of the initial Au core are studied experimentally by changing the length of the Au NRs, which are explained theoretically by the coupled harmonic oscillator model. The calculated coupled coefficients between SPR of the Cu S shell and LSPR of the Au NRs is 180 meV, which is much stronger than that of TSPR of Au NRs of 55 meV. Finally, the enhanced photothermal effect of Au@Cu S NRs has been demonstrated.

In this study,v ia as imple one-step method, chiral copper sulfide quantum dots (d/l-QDs) were prepared using d-/l-penicillamine (d-/l-Pen). The anisotropyfactor of d/l-QDs was as high as 0.01. The d/l-QDs can be used as photocatalysts to cleave proteins.N otably,t he l-QDs displayed the highest catalytic performance under left-circularly polarized light irradiation. Mechanistic investigations indicate the generation of hydroxylr adicals as the reactive species that cause the cutting of proteins.Chirality,which is usually based on organic molecules, [1] has been extended to inorganic nanomaterials such as metal nanoparticles (NPs), [2] carbon NPs, [3] semiconductor NPs, [4] ZnO films, [5] metaphotonic nanostructures, [6] NP assemblies with chiral geometries, [7] and so on.
