Multimodal biosensing systems based on metal nanoparticles

“…This nanostructure was utilized as a substrate, enabling nanoprobes to bind to a greater number of enzyme molecules. 78 In contrast to other particle sizes, the nanoscale particle size can change the conventional periodic boundary of the crystal, which gives MNPs the physical and chemical properties needed for biosensing, such as superparamagnetism and special spectra. For instance, Shen et al developed superparamagnetic Fe-Co nanoprobes that could be easily separated through magnetic adsorption, enabling the recycling of metal nanoprobes and reducing the cost associated with the reuse of biosensors.…”

Freezing-assisted reverse microemulsion synthesis of hollow mesoporous silica encapsulated glucose oxidase

“…Biomolecules have been widely used in catalysis, 1,2 pharmaceuticals [3][4][5][6] and sensors, [7][8][9] which largely depend on the immobilization of biomolecules onto or within a suitable matrix while ensuring their activity simultaneously. 10,11 Therefore, exploiting a new method for immobilizing bioactive substances into nanomaterials and maintaining their high bio-activity has been one of the most important tasks in biomedical applications in recent years. This biomolecule immobilization technology can not only reduce the cost of biomolecule separation from the reaction mixture, but also improve the stability of biomolecules during the reaction.…”

Enzyme-free electrochemical sensor platforms based on transition metal nanostructures for clinical diagnostics

“…[23][24][25][26][27] Due to its benets of affordable fabrication, improved electrochemical redox characteristics, long-term durability, superior reproducibility, etc., the enzyme-free electrochemical detection of lactic acid and glucose has received serious consideration and made signicant development in recent years. 28,29 Over recent years, there have been several enzyme-free electrochemical sensors utilizing a variety of nanostructured materials, comprising noble metallic nanoparticles (gold (Au), platinum (Pt), silver (Ag), and their alloy metals), [30][31][32] transition metal oxides (copper oxide (CuO), nickel oxide (NiO), manganese oxide (MnO 2 ), Co 3 O 4 , and their nanocomposites), 33,34 graphene nanocomposites, 35 metal-organic frameworks, 36,37 and transition metal chalcogenides, 15,[38][39][40][41][42][43][44][45] were developed.
