“…Li et al 70 prepared core−shell NGs wherein nanocrystals of NaYF4:Yb 3+ -Er 3+ (100−300 nm) were synthesized to obtain the core part and PNIPAM gel enrichment with an RhB derivative (RhBHA) as the shell part (thickness = 12 nm). The multistimulus response was investigated against the temperature, pH, and metal-ion type (Ag + , K + , Na + , Hg 2+ , Zn 2+ , and Cu 2+ ) by photoluminescence testing.…”

Fast technological progress has sped up the growth of telemedicine, mobile e-health services, and healthcare monitoring, which, nowadays, are technologies in high demand in the medical field and analytical sensing. Biosensing device design has promoted forefront research topics wherein new sensing technologies have been developed. In this regard, nanomaterials have had a crucial role wherein novel biosensors based on nanomaterials have emerged as detective tools for several biomolecules. Most biosensors are remarkably sensitive and selective to detect cancer biomarkers, toxins in foods, drugs, pathogenic microorganisms, cholesterol, pesticides, nucleic acids, glucose, heavy-metal contaminations, and other bioanalytes under different platforms at extraordinarily low concentrations (nanomolar, picomolar, or femtomolar). A comprehensive review of nanomaterials used for healthcare biosensing is offered herein. Specifically, this review offers a new point of view, highlighting and covering exhaustively several kinds of nanomaterials (<500 nm) to detect human diseases through biosensing. In this sense, we organize them into organic, inorganic, and carbon-based, thus offering a guide to selecting the best nanomaterial for specific detection. Further, it provides a roadmap to the real-time utilization of nanomaterials at a commercial scale. Also, this review addresses some crucial aspects of nanomaterials use and applications for healthcare biosensing. The progress discussed in this paper highlights the immense potential to implement the use of nanomaterials and nanocomposites in the initial examination of diseases and point-of-care testing.

“…An alternative to this architecture is the incorporation of various kinds of nanoparticles within a nanogel shell. Li and co-workers produced such a structure using NaYF 4 :Yb 3+ –Er 3+ nanocrystals as the core and a thermo-responsive nanoshell comprising of a free radically polymerised N -isopropylacrylamide and N -acrylyl- N ′-rhodamine B acylhydrazine thiourea nanogel (pNIPAm-RhBHA) [246]. In the presence of 0.0–0.099 mM of Hg 2+ , the rhodamine moieties were transformed to 1,3,4-oxadiazoles, causing fluorescence, as illustrated in Figure 11b.…”

In recent years, an increasing number of nanomaterials have been explored for their applications in biomedical diagnostics, making their applications in healthcare biosensing a rapidly evolving field. Nanomaterials introduce versatility to the sensing platforms and may even allow mobility between different detection mechanisms. The prospect of a combination of different nanomaterials allows an exploitation of their synergistic additive and novel properties for sensor development. This paper covers more than 290 research works since 2015, elaborating the diverse roles played by various nanomaterials in the biosensing field. Hence, we provide a comprehensive review of the healthcare sensing applications of nanomaterials, covering carbon allotrope-based, inorganic, and organic nanomaterials. These sensing systems are able to detect a wide variety of clinically relevant molecules, like nucleic acids, viruses, bacteria, cancer antigens, pharmaceuticals and narcotic drugs, toxins, contaminants, as well as entire cells in various sensing media, ranging from buffers to more complex environments such as urine, blood or sputum. Thus, the latest advancements reviewed in this paper hold tremendous potential for the application of nanomaterials in the early screening of diseases and point-of-care testing.
