Millions of tonnes of agro-industrial waste are generated each year globally, with the vast majority of it going untreated, underutilized, and disposed of by burning or landfilling, causing severe environmental distress and economic downturn. A practical solution to this global issue is to use green chemistry to convert this waste into value-added products. Accordingly, in the present study, agro-industrial orange peel waste was valorized into fluorescent nanodiamond-like carbon sensor via a green route involving hydrothermal treatment of microwave carbonized orange peel waste. The developed sensor, used for the fluorescence detection of potentially hazardous drug atropine sulfate, exhibits unique dual linearity over concentration ranges of 300 nM to 1 M and from 1 M to 10 M, as well as ultra-low sensitivity of 34.42 nM and 356.46 nM, respectively. Additionally, the sensor demonstrates excellent reproducibility, high stability, and satisfactory recovery when used to identify and quantify atropine sulfate in biological samples and commercially available pharmaceuticals, indicating promising multidisciplinary applications.

全球每年产生数百万吨的农业工业废物，其中绝大多数未经处理、未充分利用，并通过焚烧或填埋的方式处理，造成严重的环境问题和经济衰退。解决这一全球性问题的一个切实可行的方法是使用绿色化学将这些废物转化为增值产品。因此，在本研究中，通过涉及微波碳化橙皮废物的水热处理的绿色途径，将农业工业橙皮废物转化为荧光纳米金刚石类碳传感器。开发的传感器用于潜在危险药物硫酸阿托品的荧光检测，在 300 nM 至 1 M 和 1 M 至 10 M 的浓度范围内表现出独特的双线性，以及 34.42 nM 和 356.46 nM 的超低灵敏度， 分别。
