“…They found that the supramolecular recognition between the hyper-branched polymer and glucose or ATP anion (adenosine-5 0 triphosphate, ATP 2À ) changed the electron transfer during the redox process of ferrocene, making it a promising candidate for biosensing. 249,250 To avoid the leeching of the mediator from the electrode and to get better sensitivity and linearity, Singh et al designed a copolymer through the direct electrochemical polymerization of pyrrole and ferrocenecarboxylate modified pyrrole on indium-tin-oxide (ITO) substrate. By incorporating glucose oxidase into the copolymer film, this film showed fast detection of glucose within 3 s and with linearity up to 16.8 mM.…”

A survey of the most recent progress in the biomedical applications of metal-containing polymers is given. Due to the unique optical, electrochemical, and magnetic properties, at least 30 different metal elements, most of them transition metals, are introduced into polymeric frameworks for interactions with biology-relevant substrates via various means. Inspired by the advance of metal-containing small molecular drugs and promoted by the great progess in polymer chemistry, metal-containing polymers have gained momentum during recent decades. According to their different applications, this review summarizes the following biomedical applications: 1) metal-containing polymers as drug delivery vehicles; 2) metal-containing polymeric drugs and biocides, including antimicrobial and antiviral agents, anticancer drugs, photodynamic therapy agents, radiotherapy and biocide; 3) metal-containing polymers as biosensors, and 4) metal-containing polymers in bioimaging.

Dendrimers exhibiting reversible redox properties have attracted extensive attention for their potential as electron transfer mediators, catalysts, and molecular sensors. In this study, we introduce intriguing G1 and G2 dendrimers featuring double-decker silsesquioxane cores and silylferrocene moieties. Through a carefully orchestrated sequence of condensation, reduction, and hydrosilylation reactions, these compounds were synthesized and comprehensively characterized spectroscopically and spectrometrically. Our investigation also encompassed the examination of their properties, including thermal stability, solubility in common organic solvents, and electrochemical behavior. We determined that these dendrimers possess the capability to form monolayers on platinum electrodes, which we conclusively demonstrated through the probing of cyclic voltammetry, electrochemical impedance spectroscopy, and scanning electron microscopy imaging. Notably, this study marks the first-ever example of modifying doubledecker silsesquioxane cores with ferrocene groups while simultaneously representing one of the scarce instances of dendrimers exhibiting an open double-decker silsesquioxane core.

“…In particular, the 3D-honeycomb-like porous structure of a RGO-PU nanomaterial architectures had the advantages of ease of preparation, high porous surface structure, fast response, ultra-sensitivity, selectivity, stability, good reproducibility and repeatability (Moazzami Gudarzi et al, 2011). The 3D hierarchical nanomaterials offer porous structures made to their adjacent nano-units and large specific surface areas to supply many active sensing sites, which attracts more studies for electrochemical sensor application (Gupta et al, 2015;Xiao et al, 2014). The merit of this technique lies in its low-cost, non-use of toxic agent and easily scalable.…”
