Synthesis of Ag doped ZnlnSe ternary quantum dots with tunable emission

Abstract

Ag:ZnInSe QDs with extremely good stability, good biocompatibility, low cytotoxicity and continuously tunable wavelengths from 504 nm to 585 nm.

Polypyrrole Composite Nanoparticles with Morphology‐Dependent Photothermal Effect and Immunological Responses

“…[ 21 ] Dendritic cells (DCs), one of the most important antigen presenting cells, [ 22 ] play an important role in the initiation and regulation of innate and adaptive immunities. In order to investigate how immune system responds to PCNs, bone marrow-derived DCs separated from BALB/c mice are incubated with PPy nanoparticles, the spherical nanocomposites (SDS-5) and the raspberry-like ones (SDS-160) at a concentration of 50 µg mL −1 for 12 h. We fi nd that the SDS-160 is able to up-regulate the expression of CD80 and CD86 ( Figure 4 a and Figure S11, Supporting Information), costimulatory molecules that mark the maturation of DCs, [ 23 ] and the secretion levels of interleukin 1β (IL-β) and interleukin 12 (IL-12) signifi cantly after incubation (Figure 4 b), while the spherical nanocomposites (SDS-5) and pure PPy nanoparticles show much weaker effects.…”

In Situ Formed Fibrin Scaffold with Cyclophosphamide to Synergize with Immune Checkpoint Blockade for Inhibition of Cancer Recurrence after Surgery

“…Treg cells in the TME affect both therapeutic effect and the prognosis of the patients. [30][31][32] As a chemotherapeutic drug, CTX not only has obvious therapeutic effects on various tumors, but also acts as an immune modulator. We examined the immune effects in mice bearing 4T1 tumors handled with PBS, gel only, CTX + Gel (adding CTX and gel, respectively) , CTX@Gel gel (gel loading CTX; gel, 200 µL per mouse; CTX, 25 mg kg −1 ).…”

A facile route to aqueous Ag:ZnCdS and Ag:ZnCdSeS quantum dots: Pure emission color tunable over entire visible spectrum

“…However, the as-prepared QDs have hydrophobicity due to the surface organic capping ligand, leading to them not being suitable for the biolabeling application. The second one is aqueous synthesis, which has been proven to be a simpler, cheaper, and greener method to prepare aqueous QDs [2]. However, the QDs synthesized by this method usually suffer from some problems such as poor crystallinity and low PL QY.…”

“…Semiconductor quantum dots (QDs) have been extensively investigated in the past two decades because of their size/composition-dependent optical properties [1][2][3][4][5][6][7]. In contrast to traditional intrinsic QDs, doped QDs have recently attracted a great deal of attention because of their high photoluminescence quantum yield (PL QY), long luminescence excited state lifetimes, large Stokes shifts, thermally stable luminescence, and tunable emission colors [8][9][10][11][12][13][14][15][16][17][18][19].…”
