“…The fact that nanomaterials can be synthesized in different sizes, shapes, distributions, and compositions makes them unique for biosensor applications [14]. The nanotechnological approach is indispensable for biosensor design, as it ensures superior optoelectronic, electrical conductivity, catalytic activity, and biocompatibility properties as a result of a high surface-to-volume ratio [14,17]. Due to these unique multi-functional properties, many researchers have recently focused on the use of various nanomaterials in biosensors.…”

“…Another metal-based nanostructure widely used in biosensor applications is metal-oxide nanoparticles (MO NPs). Many different forms of synthesized nano-sized metal oxides have many uses as transducers in biosensors, and many studies are being conducted on them [17]. Karakuş et al [39] synthesized novel green polyphenol matrix CuO nanoparticles with the help of matcha tea powder extract by a low-cost, easy, green, and fast sonochemical method and then studied the development of the biosensor for the smartphone-based digital colorimetric detection of ammonia.…”

“…[16]. When a physicochemical signal such as specific temperature, sound, light, weight or pressure is produced by the interaction of the bioreceptor with the analyte, the transducer converts it into a readable or measurable electrical signal [17]. Generally, biosensors can be classified according to the type of biorecognition element and transducer [18,19].…”

In recent years, there has been significant interest in advanced nanobiosensor technologies with their exceptional properties for real-time monitoring, ultra-sensing, and rapid detection. With relevant experimental data, highly selective and hypersensitive detection of various analytes is possible using biosensors based on nanostructures. In particular, biosensors focus on vital issues such as disease early diagnosis and treatment, risk assessment of quality biomarkers, food-water quality control, and food safety. In the literature, there has been great attention to the preparation and sensing behavior of several nanomaterials-based sensors, such as polymer frameworks, metal-organic frameworks, one-dimensional (1D) nanomaterials, two-dimensional (2D) nanomaterials, and MXenes-based sensors. This chapter gives points to all aspects of fabrication, characterization, mechanisms, and applications of nanostructures-based biosensors. Finally, some smart advanced sensing systems for ultra-sensing nanoplatforms, as well as a comprehensive understanding of the sensor performances, current limitations, and future outlook of next-generation sensing materials, are highlighted.

Advanced electrocatalytic materials based biosensors for cancer cell detection – A review

Herein, we have highlighted the latest developments on biosensors for cancer cell detection. Electrochemical (EC) biosensors offer several advantages such as high sensitivity, selectivity, rapid analysis, portability, low‐cost, etc. Generally, biosensors could be classified into other basic categories such as immunosensors, aptasensors, cytosensors, electrochemiluminescence (ECL), and photo‐electrochemical (PEC) sensors. The significance of the EC biosensors is that they could detect several biomolecules in human body including cholesterol, glucose, lactate, uric acid, DNA, blood ketones, hemoglobin, and others. Recently, various EC biosensors have been developed by using electrocatalytic materials such as silver sulfide (Ag2S), black phosphene (BPene), hexagonal carbon nitrogen tube (HCNT), carbon dots (CDs)/cobalt oxy‐hydroxide (CoOOH), cuprous oxide (Cu2O), polymer dots (PDs), manganese oxide (MnO2), graphene derivatives, and gold nanoparticles (Au‐NPs). In some cases, these newly developed biosensors could be able to detect cancer cells with a limit of detection (LOD) of 1 cell/mL. In addition, many remaining challenges have to be addressed and validated by testing more real samples and confirm that these EC biosensors are more accurate and reliable to measure cancer cells in the blood and salivary samples.

Metallic nanoparticles (NPs) have great potential for biological and chemical sensor applications because the surface of the NPs has a sensitive spectral response, and the light signal can be easily monitored by their absorption or scattering. In particular, silver nanoparticles (Ag NPs) are used in various applications due to their advanced physicochemical properties such as their excellent antibacterial, catalytic, and conductivity at the nanoscale. Plant-mediated synthesis methods have come to the fore with the green chemistry approach in the synthesis of NPs. The aim of this chapter is to provide a detailed resource by considering the studies in the literature on the use of Ag NPs produced by green routes mainly in the fields of photocatalysis, sensing, and imaging. Additionally, this chapter aims to determine the importance and potential of plant-mediated synthesized Ag NPs in these applications will be determined and to be a guide for industrial and academic personnel working in this field.
