In this present study, a fluorescent probe was developed to detect curcumin, which is derived from the rhizomes of the turmeric. We used a simple and economical way to synthesize boron and nitrogen co-doped carbon dots (BNCDs) by microwave heating. The maximum emission wavelength of the BNCDs was 450 nm at an excitation wavelength of 360 nm. The as-prepared BNCDs were characterized by multiple analytical techniques such as transmission electron microscopy, X-ray photoelectron spectroscopy, X-ray diffraction, and infrared spectroscopy. Curcumin is a biologically active constituent of turmeric [1] which exhibits some biological and pharmacological activities such as antiinflammatory, [2] anti-ischemic, [3] antibacterial, [4] hepatoprotective, [5] anticarcinogenic, [6] and anti-dyspeptic [7] properties. It has also been reported that curcumin resists the formation of free radicals effectively such as superoxide radicals and hydroxyl radicals in blood and body tissues. [8,9] Due to the widespread application of curcumin in pharmacology and clinical medicine, much attention has been paid by researchers. Therefore, many methods for the detection of curcumin have been developed, including capillary electrophoresis, [10] high-performance thin-layer chromatographic, [11] high-performance liquid chromatography, [12,13] voltammetry, [14] liquid-liquid microextraction, [15] liquid chromatography-mass spectrometry, [16,17] and electrochemical techniques. [18] However, the majority of these Abbreviations used: BNCD, boron and nitrogen co-doped carbon dot; BSA, bovine serum albumin; CD, carbon dot; IFE, inner filter effect; PBS, phosphatebuffered solution; IR, infra-red; QY, quantum yield; TEM, transmission electron microscopy; UV, ultraviolet; XPS, X-ray photoelectron spectroscopy; XRD, X-ray diffraction.

Hereby, one kind of facile carbon dots (CDs) from hydroxypropylmethyl cellulose (HPMC) has been successfully provided, which obviously emitted blue fluorescence. With the related characterizations in detail, the CDs prepared here mainly consisted of C and O, owing to the functional groups of -OH and C=O on their surfaces. Likewise, the CDs also showed multiple advantages, including excellent photostability, superior dispersity and desirable stability. Moreover, the CDs were applied for sensing ciprofloxacin due to forming complexes with ciprofloxacin, thus leading to the fluorescence quenching of CDs. This proposed method was permitted to sense ciprofloxacin in a linear range of 10 nM L -1 -90 μM L -1 , suggesting that it may broaden the sensing ways for assaying ciprofloxacin.Keywords Carbon dots, assay, ciprofloxacin
