Multifunctional dendritic molecular probe for selective detection of Cu²⁺ ions using potentiometric and fluorometric techniques

Abstract

We have designed and synthesized a multifunctional dendritic molecular probe that selectively detects Cu2+ ions via potentiometric and fluorometric techniques with low detection limits (3.5 μM in potentiometry, 15 nM in fluorometry).

Electrochemical sensors for oral biofilm–biomaterials interface characterization: A review

“…Similarly, Ca 2+ is another important analyte to understand the biofilm‐mediated corrosion process as well as dental materials–biofilm local interaction. We recently developed an electrochemical method for designing new dental composites by using scanning electrochemical microscopy (SECM) or a bottom‐up chemical approach (Harris et al., 2016; X. Liu et al., 2011; Sheet et al., 2021; Sheet & Koley, 2019). SECM is a surface probe technique in which the tip or the chemical probe is positioned at a known distance above the substrate at micrometer precision, without touching it, with the aid of an amperometry approach curve.…”
