“…The direct, cost-effective, rapid electrochemical deposition and growth of DGNs from the aqueous solution of HAuCl 4 via potentiostatic methods could be performed on a polycrystalline gold surface at a potential of 0.0 mV (vs. Ag/AgCl/KCl 3 mol L −1 ) for 600 s [20], on a glassy carbon (GC) electrode at a potential of −0.3 mV (vs. Ag/AgCl) for 3600 s [21], or by a square-wave voltammetry technique using lower and higher potentials of −0.8 V and +0.2 V (vs. Ag/AgCl/NaCl 3 mol L −1 ) at a frequency of 40 Hz for 2000 s [22], on GC electrode premodified with reduced graphene oxide functionalized by β-lactoglobulin at −0.4 V (vs. Ag/AgCl/KCl sat. ) for 120 s [23], on fluorine-doped tin oxide (FTO)-coated glass at −0.25 V (vs. Ag/AgCl) for 300 s [24], on GC electrode premodified with multiwalled carbon nanotubes and gold nanoparticle hybrid (MWCNT-AuNPs) structure using chronoamperometry at a constant −0.30 V potential (vs. Ag/AgCl) for 1500 s [25], or a paper fiber-based electrode at −0.08 or −0.20 V (vs. Ag/AgCl) for 4 min [26]. It is known that the selected potential has impact on the morphology and size of electrodeposited gold nanostructures [27].…”

“…On the GC electrode formed an MWCNT-AuNPs/DGNs nanohybrid with enhanced catalytic activity that was used for acetaminophen detection in human urine [25]. Additionally, DGNs were used for the nonenzymatic detection of glucose in neutral and alkaline pH solutions [13,[20][21][22]24,26]. An enhanced electrocatalytic oxidation of glucose at lower potentials than for some other goldbased electrodes (+0.38 V vs. Ag/AgCl/NaCl 3 mol L −1 ) [22], a low limit of detection (LOD) (0.05 mmol L −1 [21], 0.005 mmol L −1 [24]), high stability for a longer period of time, lower coast, good sensitivity to glucose (37.29 µA cm −2 mM −1 [24], 190.7 µA cm −2 mM −1 [21]), wide linear range (0.1-25 mmol L −1 ), good repeatability, quick response (less than 2 s), possibility to detect glucose in a wide pH interval [21] were experimentally determined.…”

In this research, we have demonstrated a one-step electrochemical deposition of dendritic gold nanostructures (DGNs) on a graphite rod (GR) electrode without any template, seeds, surfactants, or stabilizers. Three electrochemical methods, namely, constant potential amperometry (CPA), pulse amperometry, and differential pulse voltammetry, were used for DGN synthesis on GR electrode and further application in enzymatic glucose biosensors. Formed gold nanostructures, including DGNs, were characterized by a field emission scanning electron microscopy. The optimal concentration of HAuCl4 (6.0 mmol L−1), duration of DGNs synthesis (400 s), electrodeposition potential (−0.4 V), and the best electrochemical method (CPA) were determined experimentally. Then the enzyme, glucose oxidase, was adsorbed on the surface of DGNs and covalently cross-linked with glutaraldehyde vapor. The enzymatic glucose biosensor based on DGNs electrodeposited at optimal conditions and modified with glucose oxidase showed a quick response (less than 3 s), a high saturation current (291 μA), appropriate linear range (up to 9.97 mmol L−1 of glucose, R2 = 0.9994), good repeatability (RSD 2.4, 2.2 and 1.5% for 2, 30, 97 mmol L−1 of glucose), low limit of detection (0.059 mmol L−1, S/N = 3) and good stability. Additionally, this biosensor could be successfully applied for glucose determination in real samples with good accuracy. These results proved the principle of enzymatic glucose biosensor development based on DGNs as the basis for further investigations.

“…One of the closest competitors to inkjet printing technology is screen printing. Screen printing technology is more widely adopted in biosensor fabrication [212]. However, the biggest disadvantage of screen printing is its subtractive nature, which results in a large amount of precious ink wastage [210].…”

Inkjet Printing: A Viable Technology for Biosensor Fabrication

Printing technology promises a viable solution for the low-cost, rapid, flexible, and mass fabrication of biosensors. Among the vast number of printing techniques, screen printing and inkjet printing have been widely adopted for the fabrication of biosensors. Screen printing provides ease of operation and rapid processing; however, it is bound by the effects of viscous inks, high material waste, and the requirement for masks, to name a few. Inkjet printing, on the other hand, is well suited for mass fabrication that takes advantage of computer-aided design software for pattern modifications. Furthermore, being drop-on-demand, it prevents precious material waste and offers high-resolution patterning. To exploit the features of inkjet printing technology, scientists have been keen to use it for the development of biosensors since 1988. A vast number of fully and partially inkjet-printed biosensors have been developed ever since. This study presents a short introduction on the printing technology used for biosensor fabrication in general, and a brief review of the recent reports related to virus, enzymatic, and non-enzymatic biosensor fabrication, via inkjet printing technology in particular.

A nanocomposite, rGO/AuNPs, was synthesized simultaneously using one-pot approach with gold nanoparticles (AuNPs) and reduced graphene oxide (rGO) within gelatin which used as a reducing and stabilizing agent. Then, the fabricated nanocomposites were characterized by UV-Vis, transmission electron microscope (TEM) and field emission scanning electron microscope (FE-SEM). The optimal nanocomposite was determined using electrochemical approaches. After facile and eco-friendly synthesis of rGO/AuNPs nanocomposites, it was used to fabricate the bioanode of enzymatic glucose biosensors. After drop-casting the nanocomposites on a screen-printed electrode (SPE), the glucose oxidase (GOx) was immobilized on the pre-treated SPE through a protein cross-linking approach using glutaraldehyde (GA) as a crosslinking reagent and 2,5-dihydroxybenzaldehyde (DHB) as a mediator to improve the electrochemical performance. Then, electrochemical performance of enzyme immobilized nanocomposites was studied using the potentiostat. The results demonstrate that the enzymatic biosensor made of rGO/AuNPs nanocomposites showed enhanced the sensitivity of selectivity for detection of glucose.
