“…Alternatively, nanoparticles such as multi-walled carbon nanotubes (MWCNTs) and Fe 3 O 4 have been used as mediators [16][17][18][19][20] because of their unique structure, high chemical stability, physical properties, high surface area, relatively good conductivity and desirable biocompatibility [21][22][23]. The combination of MWCNTs and Fe 3 O 4 is a developed practical strategy for an improvement in the electrode performance, because the combination of them exhibits synergistic effects toward target analysis [24,25].…”

“…(PMDTPP) (Scheme 1) was studied based on theirs piked carbon paste electrodes in aqueous solutions for the first time.T he common feature of these bisphosphoramidate compounds arises from the presenceofsymmetrical alkyldiamine in their structure, providing aq uasireversible electron transfer character for these compounds,a nd making them suitable as mediators in the electrochemical studies [26].F urthermore,t he interaction of four bisphosphoramidates with DNAw as studied, and the results showed that their carbon paste electrodes can be used as DNAs ensing devices.…”

Bisphosphoramidates are known as anticancer, antibacterial, antiviral drugs and enzyme inhibitory agents. These compounds are electroactive and insoluble in aqueous media. Hence, a comprehensive study about the electrochemical properties of them seems very interesting. The oxidative behaviors of some bisphosphoramidates were studied in buffer solution over a wide pH range by cyclic voltammetry and differential pulse voltammetry using spiked carbon paste electrodes. The interaction of these compounds with calf thymus DNA (CT‐DNA) showed the ability of these compounds as DNA sensing. The decrease in the anodic peaks of bisphosphoramidates in the presence of DNA was used for the DNA monitoring.

“…In addition, to generate suitable surface structure or functionality and thus getting controllable properties, the bare QDs need to be modified with various ligands. There have been several approaches (e.g., bi‐functional covalent linkage, ligand‐exchange, and self‐assembly) to generate QDs with high biocompatibility, water‐solubility, and monodispersity, while their long‐term stability and optical properties be maintained or improved .…”

A novel CdS quantum dots (QDs) were successfully synthesized in aqueous phase using poly (acrylic acid) grafted onto starch (starch-g-PAA). UV-vis spectroscopy, fluorescence spectroscopy, transmission electron microscopy (TEM), and Fourier transform infrared (FT-IR) techniques proved that the prepared starch-capped CdS QDs are composed of a CdS core and a polymeric shell with homogeneous size distributions. In order to study its biological behavior, multi-spectroscopic techniques were adopted to investigate their conjugation with human serum albumin (HSA) and bovine serum albumin (BSA) proteins. The recorded UV-vis spectra, cyclic voltammetry (CV) analysis, and the calculated rate of HSA and BSA fluorescence quenching by the QDs demonstrated that the interaction between them leads to the formation of QDs-HSA and QDs-BSA complexes. Moreover, FT-IR spectra showed the conformational changes of the protein in the presence of obtained QDs, indicating the presence of interaction between modified QDs and proteins.
