In a study which is first of its kind, florescent carbon nanodots (CNDs) were synthesized from jellyfish harvested off Cochin Sea using hydrothermal carbonization method. The synthesized CNDs were characterized by different techniques including, Ultraviolet–visible spectroscopy, Fluorescence spectroscopy, Fourier-transform infrared spectroscopy (FTIR), Differential scanning calorimetry (DSC), Atomic force microscopy (AFM), Transmission electron microscopy (TEM) and zeta potential. FTIR spectroscopic results showed that the CNDs were rich with CO and C-O groups. Microstructure examination of CNDs using AFM and TEM, revealed the spherical shape of CNDs with about 50 nm diameter. A nylon net surface treated with 1% of CNDs shows good fluorescence under the UV light source. CNDs can have potential application in the area of tracing abandoned, lost and discarded fishing gear (ALDFG) in ocean and also in studying the fish behaviour either as attractant or deterrent.

在一项开创性的研究中，荧光碳纳米点 (CND) 是使用水热碳化法从科钦海收获的水母中合成的。合成的 CNDs 通过不同的技术进行表征，包括紫外-可见光谱、荧光光谱、傅里叶变换红外光谱 (FTIR)、差示扫描量热法 (DSC)、原子力显微镜 (AFM)、透射电子显微镜 (TEM) 和 zeta 电位. FTIR光谱结果表明CNDs富含CO 和 CO 组。使用 AFM 和 TEM 对 CNDs 进行微观结构检查，发现 CNDs 呈球形，直径约为 50 nm。用 1% CNDs 处理的尼龙网表面在紫外光源下显示出良好的荧光。CND 在追踪海洋中遗弃、丢失和丢弃的渔具 (ALDFG) 以及研究鱼类行为（作为引诱剂或威慑物）方面具有潜在应用。
