“…The nanocomposite was stable during 8 cycles of sensing glucose, the reason can be attributed to synergistic effect of PVP and CuSe which enhances the available surface area for the reaction as well as there was no need of binder between glassy carbon electrode and nanocomposite. [49][50][51]…”

“…We believe this metallic ingredient can replace the metal in MOF to be a better electrical trigger [ 34 ] because of its better conductivity [ 35 ] as a proven semiconductor ingredient [ 36 , 37 ]. However, several problems, such as glucose oxidation [ 38 , 39 , 40 ], low binding affinity [ 41 ], and Cu toxicity [ 42 ], need to be solved first. The first generation of electrical biosensors is the enzyme-based amperometric biosensor [ 43 , 44 ], resulting in glucose-oxidised problems with a reduction–oxidation (redox) microenvironment for tumour growth [ 45 ].…”

“…The first generation of electrical biosensors is the enzyme-based amperometric biosensor [ 43 , 44 ], resulting in glucose-oxidised problems with a reduction–oxidation (redox) microenvironment for tumour growth [ 45 ]. This could be solved by using non-enzymatic glucose sensors (NEGS) [ 40 , 44 ]. The second problem is the low active pharmaceutical ingredients (API)-binding affinity, resulting in a lower API cargo carrier and a lesser choice of API variations.…”

This paper is to discuss the potential of using CuZn in an electrical biosensor drug carrier for drug delivery systems. CuZn is the main semiconductor ingredient that has great promise as an electrochemical detector to trigger releases of active pharmaceutical ingredients (API). This CuZn biosensor is produced with a green metal of frameworks, which is an anion node in conductive polymers linked by bioactive ligands using metal–polymerisation technology. The studies of Cu, Zn, and their oxides are highlighted by their electrochemical performance as electrical biosensors to electrically trigger API. The three main problems, which are glucose oxidisation, binding affinity, and toxicity, are highlighted, and their solutions are given. Moreover, their biocompatibilities, therapeutic efficacies, and drug delivery efficiencies are discussed with details given. Our three previous investigations of CuZn found results similar to those of other authors’ in terms of multiphases, polymerisation, and structure. This affirms that our research is on the right track, especially that related to green synthesis using plant extract, CuZn as a nanochip electric biosensor, and bioactive ligands to bind API, which are limited to the innermost circle of the non-enzymatic glucose sensor category.

“…Recently, the enzymatic and non-enzymatic electrochemical [ 31 ], neuron fibers [ 32 ], nitrogen-doped graphene quantum dots [ 33 ], and plasmonic [ 34 ] systems have been experimentally tested for glucose sensing in the literature. Also, theoretically, the CDs nanoparticules [ 35 ], boronic acid decorated graphene nanoflakes [ 36 ], nanocages [ 37 ] are complexed with the glucose entity for adsorption application. In our paper, we have turned to other interesting sensor systems (ZnO clusters).…”
