RETRACTED: Simple and sensitive molecularly imprinted polymer-MPA capped Mn-doped ZnS quantum dots-based phosphorescence probe for cyanotoxins determination in algae metabolites

摘要: Abstract This paper aimed to develop a simple method for detection and quantification of cylindrospermopsin (CYN) in the water sample. The novel biosensor was based on molecular imprinted Mn-doped ZnS quantum dots. Two fragments which mimicked partial structure CYN were carefully selected synthesize molecularly 3-mercaptopropionic acid-capped Mn-ZnS dots (MPA-MnZnS-QDs-MIPs). As two fragment sites could enhance rebinding into them modulated QDs’ selective aggregation MPA-MnZnS-QDs-MIPs. Hence, enhanced room temperature phosphorescence (RTP) response observed as MPA-MnZnS-QDs-MIPs interacted with A good linear relationship concentration range 30–320 μg L−1 limit 24 demonstrated by intensity ratio ΔP/P0. And our exhibited higher selectivity than fragments. Also, there no interference system when competitors present algae culture samples. presented required minimal expertise enabled fast inexpensive monitoring toxins.
