Hollow gold nanospheres (HGNs) are core/shell structures with a dielectric material core, usually composed of solvent, and a gold metal shell. Such structures have two metal/dielectric interfaces to allow interaction between the gold metal with the interior and external dielectric environment. Upon illumination by light, HGNs exhibit unique surface plasmon resonance (SPR) properties compared to solid gold nanoparticles. Their SPR absorption/scattering can be tuned by changing their diameter, shell thicknesses, and surface morphologies. In addition to the low toxicity, easy functionalization, resistance to photobleaching, and sensitivity to changes in surrounding medium of gold, the enhanced surface‐to‐volume ratio and tunable SPR of HGNs make them highly attractive for different applications in the fields of sensing, therapy, and theranostics. In this article, we review recent progress on the synthesis and structural control of HGNs and applications of their SPR properties in biomedical sensing and theranostics. This article is categorized under: Diagnostic Tools > Biosensing Diagnostic Tools > in vitro Nanoparticle‐Based Sensing Diagnostic Tools > in vivo Nanodiagnostics and Imaging

“…Nanoshells (NShs) are spherical nanoparticles which generally consist of a thin metallic outer shell with a dielectric core, as illustrated in Figure 10b [217]. NShs make ideal components for optical sensors, as their quantum plasma oscillation feature can be easily adjusted by manipulating the composition and size of the core and shell [218]. It is feasible to functionalise biomolecules, such as proteins, on these moieties to tailor the inertness or bioreactivity of nanoshells, making them an ideal choice for therapeutic applications and biosensing [219,220].…”

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.

“…Grabowska‐Jadach et al (2019) prepared hollow gold nanoshells (HGNs) and functionalized the selective delivery of changed nanoparticles to target cells using an ssDNA aptamer. Based on the results acquired, it has been shown that aptamer entered both line cells (HaCaT and A375) and higher aptamer concentrations (almost 2.67 times) have been identified in tumor cells [47b] . In a 2015 study, Shi et al presented Pd nanosheet surface coating (Pd‐NSs) and it's in vivo activity.…”

Hyperthermia generates heat as a cure for illness and it is not a chemical treatment. Nanomaterials are supposed to provide novel mechanisms to tackle photothermal and magnetothermal problems, with the potential also to deal with specific approaches to care. The present review outlines recent developments in the field of photothermal and magnetothermal responsive nanomaterials and the photothermal approach mechanism over the last years. These photo/magnetothermal nanomaterials are classified into gold nanostructures (various shapes), carbon nanomaterials (CNTs, fullerene, carbon quantum dots, and graphene), inorganic nanomaterials (Fe, Pt, Pd, Bi, MOF, MoSe2, inorganic quantum dots, etc.) and organic nanoparticles (PLGA (Poly Lactic‐co‐Glycolic Acid) and other nanopolymers). Different groups may be placed together to improve the potential of the photothermal/magnetothermal effects, treatments, drug delivery, and imaging. The review also describes synthesis strategies for photothermal/magnetothermal nanomaterials, physicochemical characterization, the role of size, size distribution, shape, and surface coating of nanomaterials, challenges, and future scopes of photothermal/magnetothermal responsive nanomaterials for therapy, controlled drug delivery, and imaging applications. The recent development in nanomaterial has shown great potential for tumor diagnostic and therapeutic applications in hyperthermia. Magnetic hyperthermia (also called thermal therapy or thermotherapy) is a type of cancer treatment in which body tissue is exposed to high temperatures (up to 41 °C) in presence of a magnetic field. Research has shown that high temperatures can damage and kill cancer cells, usually with minimal injury to normal tissues. By killing cancer cells and damaging proteins and structures within cells, hyperthermia can necrotize tumor cells. This treatment can be local, regional, or whole‐body hyperthermia, depending on the extent of the area being treated. Hyperthermia can be combined with anticancer drugs or chemotherapy to enhance cancer treatment. In this article, we have discussed recent nanomaterials utilized for this treatment, mechanism, and synthesis methods.
