Here we report a facile coordination-assisted method to construct a FRET-based probe that shows ratiometric detection of metal ions with improved selectivity. Probe 2 exhibits good sensitivity and selectivity towards the Fe3+ and Al3+ over other cations in aqueous acetonitrile solution. Probe 1 can be formed in situ by a convenient addition of Salen-Zn complex, which can further discriminate the Fe3+ from Al3+ with different ratiometric fluorescence responses.

Summary 外阴佩吉特病(VPD)是一种罕见的皮肤疾病,常见于绝经后的白人女性,它会引起外阴周围的皮肤瘙痒或灼烧。这种疾病有不同的类型,并且在过去,所有类型的 VPD 都与乳腺、肠道和泌尿系统的恶性肿瘤(如癌症)有关。这项来自荷兰的研究着眼于皮肤非侵入性 VPD, 其中在诊...
