“…Azmi et al,8 reported the use of ultra-sensitive, silicon nanowire-based biosensor devices for the detection of 8-hydroxydeoxyguanosine (8-OHdG), a biomarker for prostate cancer risk. Moreover, they respond to multiple physical, chemical, or biological stimuli, and consequently provide a potential means for manufacturing nano-machines 13 . Moreover, a range of nanometer-sized materials, including metal and metal oxide NPs, semiconductor quantum dots, carbon nanomaterials and polymer NPs have been used for various important pharmaceutical and medical applications (for example, nano polymerase chain reaction, nano-PCR).…”

Graphical abstract:Significant recent developments in plant-derived nanostructures, their classes, and vital applications are discussed with insight into their use as a bio-renewable, sustainable, and diversified resource for the production of useful nanostructures. AbstractPlant-derived nanostructures and nanoparticles (NPs) have functional applications in numerous disciplines such as health care, food and feed, cosmetics, biomedical science, energy science, drug-gene delivery, environmental health, and so on. Consequently, it is imperative for researchers to understand that plants are cost-effective, sustainable and renewable platforms, and therefore, they are ideal sources for production of natural NPs. This critical review discusses significant recent developments pertaining to plant-derived nanostructures, their classes, and vital applications. The aim is to provide insight into the use of plants as a bio-renewable, sustainable, diversified resource and platform for the production of useful nanostructures and NPs, with functions in various fields, including medicine, industry, agriculture, and pharmaceuticals.

“…1 The use of biotemplate makes the synthetic procedure simple and product controllable taking advantage of the nature of their own. Biotemplates like organisms (butterfly wing, 2 hair, 3 wood fiber 4,5 and pollen 6 ), microorganisms (bacteria, 7,8 fungus, 9,10 and viruses 11 ) and biological macromolecules (DNA, [12][13][14] RNA, 15 proteins, [16][17][18][19] and polysaccharides 20 ) were reported to prepare inorganic materials.…”

Eggshell membrane (ESM) is selected as biotemplate to prepare MnO 2 submicroparticles (SMPs) using Chinese Brush with sodium hydroxide solution. The size with average 710 nm of the obtained materials is in good consistency with the microsructured biotemplate. An efficient and convenient absorbent for methylene blue (MB) is developed. The removal efficiency could reach up to 93% in 35 min under room temperature without pH adjusting owing to the excellent adsorption from ESM itself and hydroxyl group formed on the surface of MnO 2 crystal in the aqueous solution. Materials on the membrane can be separated from the wastewater simply to avoid the secondary pollution caused by the leak of material. This interesting approach to MnO 2 SMPs and facile operation for MB adsorption could open a new path to the submicro-materials based wastewater treatment.

An enzymatic synthesis strategy of a DNA-template alloy nanocluster is presented. In this strategy, alkaline phosphatase (ALP) catalysed pyrophosphate (PPi) hydrolysis broke the coordination between Cu 2+ and PPi.The fluorescent DNA-template alloy nanoclusters were produced in situ through the reduction of the Cu 2+ and Ag + in the presence of single strand DNA (ss DNA). The fluorescence intensity of the alloy nanocluster was related to the concentration of ALP. This fluorescence turn-on strategy exhibited high sensitivity and selectivity for the ALP assay. Additionally, this strategy was also applied in an ALP-linked immuno-sorbent assay for a-fetoprotein (AFP) detection. Taking AFP as the model protein, it could be detected at a range from 10 ng mL À1 to 150 ng mL À1 and the detection limit was 4 ng mL À1 (0.042 nM). Finally, the diagnostic capability and practical application of this method was demonstrated by detecting AFP in human blood serum.
