Green-emissive water-dispersible silicon quantum dots for the fluorescent and colorimetric dual mode sensing of curcumin

Abstract

Curcumin, an active ingredient of Curcuma longa, which possesses good biological and pharmacological activities, is effective in treating of many diseases. Developing simple and sensitive methods for detection of curcumin...

Green-emitting silicon nanoparticles as a fluorescent probe for highly-sensitive crocin detection and pH sensing

“…As illustrated in Fig. 2c, the three peaks at 397.2 eV, 398.5 eV and 399.0 eV corresponded to N–Si, N–H and N–(C) 3 , 34 respectively. Fig.…”

Green synthesis of yellow-green emissive silicon nanoparticles and their application for the sensitive fluorescence detection of bilirubin

“…The characteristic absorption peaks at 222 nm and 435 nm were assigned to the π–π* transition of CC and the n–π* transition of CO, respectively (curve c). 28,29 The SiNP solution showed bright yellow-green fluorescence under UV irradiation at 365 nm (inset in Fig. 1A).…”

“…2D). Three fitting peaks at 101.4 eV (Si–C), 102.0 eV (Si–N) and 102.6 eV (Si–O) are displayed in the high-resolution XPS spectrum of Si 2p 28 (Fig. 2E).…”

The preparation of hybrid silicon quantum dots by one-step synthesis for tetracycline detection and antibacterial applications

“…As an emerging class of photoluminescent quantum dots, QDs have become the focus of nanomaterials because of their special photoelectric properties, excellent biocompatibility and stability. [9][10][11][12] Compared with traditional III-V (InAs, GaSb, and GaN) 13 , II-VI QDs (CdSe, ZnSe, and CdTe) 14 and other nanoparticles, [15][16][17] silicon quantum dots (SiQDs) have unique properties 18,19 including innocuousness, greenness, low cost, and high sensitivity and selectivity. Importantly, SiQDs also have the benets of good biocompatibility because they can be converted by the kidneys into silicates and excreted in the urine.…”
