“…Further, on introducing the iodine molecule, the adsorption energy of the CuIPc/DA complex is increased by ~ 13kcal/mol. This high adsorption energy is due to the presence of multiple strong hydrogen bonds ± From ref [43], # From ref [24], & From ref [44] In a previous study, the neutral dopamine molecule only showed an adsorption energy of 25.136 kcal/mol when employing boron-and nitrogen-doped single-walled carbon nanotubes in gas. Likewise adsorption energy was only − 14.758 kcal/mol in another study that involved the detection of dopamine using a metal-free nitrogen-enriched porous carbon material in a water medium.…”

“…All computations were carried out using the DFT [22] method with the beck three parameters B3LYP along with the dispersion correction D3(BJ) [23,24]. The basis set 6-31G(d, p) was used for carbon (C), hydrogen (H), nitrogen (N) and oxygen (O) atoms, whereas the LANLDZ basis set was used for the central metal copper (Cu) and iodine (I) in the Gaussian 16 program.…”

Density Functional Theory (DFT) was employed to investigate the sensing behavior of the neurotransmitter dopamine (DA) when interacting with OH-functionalized copper phthalocyanines (CuPCs) and copper phthalocyanines coadsorbed with iodine (CuIPc), both in gaseous and aqueous media. The study revealed that CuIPc demonstrates a superior capacity for detecting dopamine molecules compared to CuPc. Within these complexes, hydrogen bonds and coordination bonds were observed, with hydrogen bonds playing a pivotal role in the dopamine adsorption process. The enhanced electrical conductivity of CuPc sheets after iodine adsorption, along with the high adsorption energy of the iodine-coadsorbed CuPc/DA complexes, underscores the significance of iodine in this context. It is noteworthy that the utilization of iodine significantly enhances the sensing response for dopamine. In summary, copper phthalocyanine coadsorbed with iodine emerges as a promising material for dopamine sensors, offering possibilities for further advancements in this field.

“…The nitrogen bonded porous carbon material exhibits excellent electrochemical stability, reproducibility, sensitivity (4.64 µA µM -1 cm -2 ), and a low detection limit (2.74 nM) in detecting dopamine. The interactions of starch-based nitrogen bonded porous carbon materials with dopamine were stronger at -0.64 eV compared to oxygen-filled sheets [124] . Apart from metal oxides, graphene oxide has been widely used as a conductive substrate.…”

Biopolymers are an attractive green alternative to conventional polymers, owing to their excellent biocompatibility and biodegradability. However, their amorphous and nonconductive nature limits their potential as active biosensor material/substrate. To enhance their bio-analytical performance, biopolymers are combined with conductive materials to improve their physical and chemical characteristics. We review the main advances in the field of electrochemical biosensors, specifically the structure, approach, and application of biopolymers, as well as their conjugation with conductive nanomaterials, polymers, and metal oxides in green-based non-invasive analytical biosensors. In addition, we reviewed signal measurement, substrate bio-functionality, biochemical reaction, sensitivity, and limit of detection (LOD) of different biopolymers on various transducers.To date, pectin biopolymer, when conjugated with either gold nanoparticles, polypyrrole, reduced graphene oxide, or multiwall carbon nanotubes forming nanocomposites on glass carbon electrode transducer, tends to give the best LOD, highest sensitivity, and can detect multiple analytes/targets. This review will spur new possibilities for the use of biosensors for medical diagnostic tests.

Natural green compounds for sensor modification (binders) are challenging in electrochemistry. Starch is a carbohydrate biopolymer that has been used extensively in the development of biomaterials for the food industry due to its ability to impart textural characteristics and provide gelling or film formation. In particular, the excellent film-forming characteristics have been used for the development of new surface modifying architectures for electrodes. Here, we highlight a very comprehensive overview of the properties of interest of various types of starch in conjunction with (bio)materials in the chemical modification of sensors and biosensors. Throughout the review, we first give an introduction to the extraction, applications, and properties of starches followed by an overview of the prospects and their possible applications in electrochemical sensors and biosensors. In this context, we discuss some important characteristics of starches and different strategies of their film formation with an emphasis on their role in the development of electrochemical sensors and biosensors highlighting their main contributions to enhancing the performance of these devices and their applications in environmental and clinical samples.
