able consequences, such as organ failure, cytotoxicity, and brain damage. [6][7][8] Therefore, designing and developing a novel method to detect the concentrations of silver ions will be very significant in environmental and biological fields. To date, numerous analysis ways of monitoring Ag + ions in aqueous media were developed and they could be generalized as follows: such as atomic absorption spectrometry, inductively coupled plasma-mass spectrometry, high-performance liquid chromatography, UV-vis spectrometry, and fluorescence spectrometry. [9][10][11][12][13] Compared to the conventional methods with single signal transduction, the determination of Ag + ions with multiple responses could provide more convincing results. In this contribution, the nanoprobe can specifically detect Ag + ions not only by fluorescence via color changes but also it employs UV-vis absorption spectroscopy to recognize silver ions rapidly. The dual mode sensing is certainly superior to traditional fluorescence and the signals are collected in a more reliable way with accuracy and convenience.It has been well documented that the polydopamine (PDA) and its derivative materials have been extensively discussed in energy, catalytic, environmental, and biomedical fields. [14,15] Under alkaline conditions, the PDA was synthesized by deprotonation and intermolecular Michael addition reaction with the The condensation reaction between methyldopa sesquihydrate and ethylenediamine is reported and the assembled nanoplatform possesses green luminescence at 520 nm with excitation-independent feature. The employment of sodium borohydride during synthesis has stabilized the nanoparticle (NP) size and suppressed uncontrolled autoxidation processes. It is appealing to observe that the fluorescence as well as colorimetric titration demonstrates trace level monitoring of silver ions, and the detection limits are determined to be 68 × 10 −9 m (fluorometric) and 71 × 10 −9 m (colorimetric), respectively. The optical response to Ag + ions is assigned to a static quenching process and the corresponding redox reaction including particle aggregation may cause the "on-off " change. During in vitro studies, two living cell lines (HeLa cells and T-cells) are used and the negligible cytotoxicity of such NP is verified via flow cytometry and 3-(4,5-dimethythiazol-. 2-yl)-2,5-diphenyl tetrazolium bromide assays. More importantly, the visualization of silver recognition in two cells is realized and the availability of polydopamine-type NPs for the purpose of biomedical evaluation can generate considerable interests in future studies.

“…Among these polymers, PU has found extensive commercial and industrial applications due to its virtue of easiness of preparation and appealing mechanical properties . Of late, some work has been published relating to luminescent PU; however, to the best of our knowledge, sunlight‐activated long persistent luminescent polyurethane (LPLPU) has been scarcely reported to date.…”

An amino‐terminated long persistent luminescent phosphor (Amino‐SrAl2O4:Eu2+,Dy3+) was prepared based on inorganic SrAl2O4:Eu2+,Dy3+ phosphor, chemically modified with 3‐aminopropyltriethoxysilane (KH550). Fourier transform infrared and X‐ray photoelectron spectral, thermogravimetric and scanning electron microscopic measurements confirmed the successful synthesis of Amino‐SrAl2O4:Eu2+,Dy3+. Then this amino‐functionalized phosphor was introduced into polyurethane (PU) through urea linkages, and the effects of the chemical combination of Amino‐SrAl2O4:Eu2+,Dy3+ and PU on the morphology, structure, storage stability, and mechanical, thermal and luminescent properties of the resultant long persistent luminescent polyurethane (LPLPU) were investigated. Compared with SrAl2O4:Eu2+,Dy3+/PU composites prepared by physical blending, the LPLPU shows better mechanical properties and storage stability due to the good compatibility of Amino‐SrAl2O4:Eu2+,Dy3+ with PU. More residues and higher initial decomposition temperature are observed because the interaction of the amino‐phosphor and PU delays the degradation. Study of the luminescent effect reveals that the LPLPU shows more than 10 h afterglow after cessation of the excitation light, and the brightness of green light in darkness is basically the same as that of LPLPU and SrAl2O4:Eu2+,Dy3+/PU. © 2016 Society of Chemical Industry

“…The development of filler injection techniques allows to significantly improve the properties of the resulting materials. There are on-going investigations of novel efficient PU-based scintillators doped with various organic phosphors [106], [111], [112], [113], [114] and rare-earth elements [107], [115]. The flexibility of chemical composition of the matrix allows to securely stabilize particles with high active surface area.…”
