Abstract：
UNASSIGNED: Yeast cell walls are a sustainable biomass source containing carbon and other elements like phosphorus. Converting cell walls into valuable nanomaterials like carbon quantum dots (CQDs) is of interest.
UNASSIGNED: Cell walls from Saccharomyces cerevisiae were hydrothermally treated in 0.5 M H2SO4 to produce CQDs. Multiple analytical techniques were utilized to confirm phosphorus-doping (P-CQDs), characterize the fluorescence properties, determine quantum yield, and evaluate the sensing, antimicrobial, photocatalytic, and antioxidant capacities.
UNASSIGNED: A successful synthesis of P-CQDs was achieved with strong blue fluorescence under UV excitation, 19 % quantum yield, and excellent stability. The P-CQDs showed sensitive fluorescence quenching in response to ferric ions with a 201 nM detection limit. Antibacterial effects against Escherichia coli and Staphylococcus aureus were demonstrated. P-CQDs also exhibited dye degradation under sunlight and antioxidant activity. So, the prepared P-CQDs displayed promising multifunctional capabilities for metal ion detection, disinfection, and environmental remediation. Further research is required to fully realize and implement the multifunctional potential of P-CQDs in real-world applications.

摘要：
■酵母细胞壁是含有碳和其他元素如磷的可持续生物质来源。将细胞壁转化为有价值的纳米材料如碳量子点(CQD)是令人感兴趣的。
■来自酿酒酵母的细胞壁在0.5MH2SO4中水热处理以产生CQDs。利用多种分析技术来确认磷掺杂(P-CQDs)，表征荧光特性，确定量子产率，并评估传感，抗菌，光催化,和抗氧化能力。
■在紫外线激发下，以强烈的蓝色荧光实现了P-CQDs的成功合成，19％的量子产率，和出色的稳定性。P-CQDs响应于三价铁离子显示出灵敏的荧光猝灭,检测极限为201nM。证明了对大肠杆菌和金黄色葡萄球菌的抗菌作用。P-CQDs在阳光下也表现出染料降解和抗氧化活性。所以,制备的P-CQDs显示了金属离子检测的有希望的多功能能力，消毒,和环境修复。需要进一步的研究来充分实现和实施P-CQD在实际应用中的多功能潜力。
