“…The characterization of analytical parameters involved the determination of affinity-binding constants, detection accuracy, and figure of merit values for the minimum E-proteins’ concentration (0.08 pM) while the assay selectivity was tested against E- proteins of Zika virus ( Figure 10 ). A similar SPR immunosensor strategy, although involving the introduction of cadmium sulfide quantum dots over graphene oxide surfaces, was also applied to the detection of dengue E-proteins’ virus [ 51 ]. The optimization of protein interactions with the antibody immobilized on the graphene oxide-activated surface achieved the lowest detection limit at 1 pM, thus demonstrating less sensitivity in comparison with the composite of PAMAM dendrimers.…”

The global burden of coronavirus disease 2019 (COVID-19) to public health and global economy has stressed the need for rapid and simple diagnostic methods. From this perspective, plasmonic-based biosensing can manage the threat of infectious diseases by providing timely virus monitoring. In recent years, many plasmonics’ platforms have embraced the challenge of offering on-site strategies to complement traditional diagnostic methods relying on the polymerase chain reaction (PCR) and enzyme-linked immunosorbent assays (ELISA). This review compiled recent progress on the development of novel plasmonic sensing schemes for the effective control of virus-related diseases. A special focus was set on the utilization of plasmonic nanostructures in combination with other detection formats involving colorimetric, fluorescence, luminescence, or Raman scattering enhancement. The quantification of different viruses (e.g., hepatitis virus, influenza virus, norovirus, dengue virus, Ebola virus, Zika virus) with particular attention to Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) was reviewed from the perspective of the biomarker and the biological receptor immobilized on the sensor chip. Technological limitations including selectivity, stability, and monitoring in biological matrices were also reviewed for different plasmonic-sensing approaches.

“…The decreasing of the FOM could be due to a faster decrease in the sensitivity compared to FWHM, which resulted in a notable uncertainty in determining the position of the resonance angle. To investigate the binding between Au/DSU/amine-functionalized rGO-PAMAM/IgM-based SPR sensor and target, the changes in the resonance angle as a function of the concentration of DENV 2 E-proteins from 0.08 to 1 pM were plotted and fitted according to the Langmuir adsorption model (Figure 6), represented by the following equation [63,64]: To investigate the binding between Au/DSU/amine-functionalized rGO-PAMAM/IgM-based SPR sensor and target, the changes in the resonance angle as a function of the concentration of DENV 2 E-proteins from 0.08 to 1 pM were plotted and fitted according to the Langmuir adsorption model (Figure 6), represented by the following equation [63,64]:…”

Dengue viral infection is one of the most common deadliest diseases and has become a recurrent issue for public health in tropical countries. Although the spectrum of clinical diagnosis and treatment have recently been established, the efficient and rapid detection of dengue virus (DENV) during viremia and the early febrile phase is still a great challenge. In this study, a dithiobis (succinimidyl undecanoate, DSU)/amine-functionalized reduced graphene oxide-–polyamidoamine dendrimer (DSU/amine-functionalized rGO–PAMAM) thin film-based surface plasmon resonance (SPR) sensor was developed for the detection of DENV 2 E-proteins. Different concentrations of DENV 2 E-proteins were successfully tested by the developed SPR sensor-based system. The performance of the developed sensor showed increased shift in the SPR angle, narrow full-width–half-maximum of the SPR curve, high detection accuracy, excellent figure of merit and signal-to-noise ratio, good sensitivity values in the range of 0.08–0.5 pM (S = 0.2576°/pM, R2 = 0.92), and a high equilibrium association constant (KA) of 7.6452 TM−1. The developed sensor also showed a sensitive and selective response towards DENV 2 E-proteins compared to DENV 1 E-proteins and ZIKV (Zika virus) E-proteins. Overall, it was concluded that the Au/DSU/amine-functionalized rGO–PAMAM thin film-based SPR sensor has potential to serve as a rapid clinical diagnostic tool for DENV infection.

“…Sulfur-containing quantum dots are considered to be suitable alternative nanomaterials in biosensing applications [ 67 , 109 , 110 , 111 , 112 ]. Their stable photoelectric properties made sulfur-containing quantum dots be adapted as excellent probes in biosensors via various strategies, such as electrochemical, PEC, PL and ECL strategy [ 113 , 114 , 115 ]. Soluble sulfur-containing quantum dots can react with biomolecules, thus biosensors for detection biomolecules could be established through specific physiochemical reactions between them [ 81 , 116 , 117 ].…”

In recent years, sulfur-containing nanomaterials and their derivatives/composites have attracted much attention because of their important role in the field of biosensor, biolabeling, drug delivery and diagnostic imaging technology, which inspires us to compile this review. To focus on the relationships between advanced biomaterials and biosensors, this review describes the applications of various types of sulfur-containing nanomaterials in biosensors. We bring two types of sulfur-containing nanomaterials including metallic sulfide nanomaterials and sulfur-containing quantum dots, to discuss and summarize the possibility and application as biosensors based on the sulfur-containing nanomaterials. Finally, future perspective and challenges of biosensors based on sulfur-containing nanomaterials are briefly rendered.
