HRQoL of a group of Chinese patients with TBI improved during 2 years after discharge. Age, sex and severity of TBI were significantly associated with physical or mental HRQoL after discharge.
A water-soluble and polyethyleneimine protected copper nanoclusters (CuNCs@PEI) was prepared by one-step ultraviolet radiation (UVI) combined with microwave heating (MWH) method, and the influence of different energy suppliers on the CuNCs@PEI luminescence performance was investigated in detail. The as-prepared CuNCs@PEI could be used as a viable fluorescent probe for sensitive and selective mensurating TCH (tetracycline hydrochloride)/VB12 (vitamin B12) with a linear response in the range of 0.33-66.67/0.33-53.33 μmol L À 1 , and corresponding limit of detection (LOD) and limit of quantifica-tion (LOQ) were calculated to be 55.50/56.34 and 184.82/ 187.61 nmol L À 1 . The fluorescence (FL) quenching of CuNCs@PEI by TCH/VB12 came from the combination of FRET (Förster resonance energy transfer) and IFE (inner filter effect). Moreover, the probe was successfully extended to the assays of TCH in veterinary powder or TCH tablets and VB12 in oral liquid or VB12 tablets with satisfactory results compared to the standard HPLC method. Besides, the CuNCs@PEI probe exhibited a good temperature sensing.
Doping Ag-enhanced and glutathione-stabilized Au nanoclusters (GSH–Ag/AuNCs) were prepared by the one-step ultraviolet radiation combined with microwave heating method. The effects of the molar ratio of Au–Ag and different types of energy suppliers on the fluorescent performance of GSH–Ag/AuNCs were studied in detail. After that, a new ratio fluorescent probe (RF-probe) based on the mixing of GSH–Ag/AuNCs with carbon dots (CDs) was designed for sensitive and selective determination of copper gluconate (CG) and cupric sulfate (CS). For the CDs–GSH–Ag/AuNCs RF-probe, the fluorescence (FL) of CDs (at 440[Formula: see text]nm) and that of alloy nanoclusters (NCs) (at 605[Formula: see text]nm) were, respectively, unaffected and strongly quenched in the presence of CG/CS at [Formula: see text][Formula: see text]nm coming from the dynamic quenching process. Corresponding linear ranges and limit of detection (LOD) of the RF-probe for the CG/CS assay were estimated to be 0.17–6.20/0.17–5.62[Formula: see text][Formula: see text]mol/L and 16.80/15.95[Formula: see text]nmol/L, respectively. Furthermore, the proposed RF-probe was successfully used for the assays of CG in CG tablets and CG additive, and CS in infant formula and CS additive, respectively.
A strategy involving the effect of
the local constraint on junctions
for doping-induced phosphorescence was proposed to increase the rigidity
of hydrogen-bonded polymer to inhibit the nonradiative decay of the
organic phosphorescent dyes and was verified by bromophenol blue (BPB)
derivatives as the near-infrared (NIR) phosphorescent dye. It is shown
that the effect of local constraints on junctions of β-cyclodextrin
in the poly(vinyl alcohol) (PVA-LCPN) matrix can effectively
improve the quantum yields of NIR phosphorescence of BPB derivatives.
On the basis of the verification and optimization of the system through
response surface analysis, the quantum yield of TBPB@PVA-LCPN film based on NIR emission could be increased up to 77% compared
with that of TBPB@PVA, reaching 5.3%, and the quantum
yield in the NIR region could be improved to 3.6%. The results of
response surface analysis are consistent with the phenomenon of our
proposed strategy, which can inspire the production of organic materials
with NIR RTP emission. Together, this could inform efficient and cheap
strategies for increasing the quantum yield of the doping RTP materials.
