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

Abstract

In this study, we prepared three different silicon quantum dots (SiQDs-1, SiQDs-2 and SiQDs-3) by hydrothermal synthesis with rose Bengal as the reducing agent and triacetoxy(methyl)silane and allyloxytrimethylsilane as silicon sources.

Construction of a stable fluorescent sensor based on CsPbBr3/CdS core/shell quantum dots for selective and sensitive detection of tetracycline in ethanol

“…Quantum dots (QDs) are widely used in the eld of sensing [18][19][20][21] due to their excellent optical properties such as a broad excitation spectrum, a narrow emission spectrum, adjustable emission wavelength, and resistance to photobleaching. At present, various uorescent materials including semiconductor QDs, [22][23][24] carbon dots 25,26 and silicon QDs 27,28 have been used for uorescence detection of TC. However, the uorescence quantum yield of conventional QDs is low, and the sensitivity of the sensor will decrease aer surface modication.…”
