Phytochelatins are small peptides that can be found in several organisms, which use these oligopeptides to handle heavy metal elements. Here, we report a method for monitoring interactions between lead(ii) ions in aqueous solutions and phytochelatin 6 oligopeptide bioconjugated onto pegylated gold nanorods (PEG-AuNrs). This study is the first step towards a high sensitive label free optical biosensor to quantify heavy metal pollution in water.
植物螯合肽是一种能在多种生物体内发现的小肽，这些生物利用这些寡肽来处理重金属元素。在此，我们报告了一种监测水溶液中的铅（II）离子与缀合在聚乙二醇化金纳米棒（PEG-AuNrs）上的植物螯合肽6寡肽之间相互作用的方法。这项研究是迈向高灵敏度无标记光学生物传感器以量化水中重金属污染的第一步。
