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 - 90 μM L, suggesting that it may broaden the sensing ways for assaying ciprofloxacin.
在此，成功制备了一种由羟丙基甲基纤维素（HPMC）制成的简便碳点（CDs），其明显发出蓝色荧光。通过详细的相关表征，此处制备的碳点主要由C和O组成，这归因于其表面的 -OH和C=O官能团。同样，这些碳点还具有多种优点，包括出色的光稳定性、优异的分散性和良好的稳定性。此外，由于碳点与环丙沙星形成络合物，导致碳点荧光猝灭，因此可将这些碳点用于检测环丙沙星。该方法可在10 nM L - 90 μM L的线性范围内检测环丙沙星，表明它可能拓宽环丙沙星的检测途径。
