“…Notably, alfalfa plant, Medicago sativa [232], with the experimental evidence of various living plants preparation [233] were used for the demonstration of well known nanoparticle preparation with ground plant biomass. Several reports have shown the potential applications of various plant parts, including leaves [234,235], seeds [236], flowers [237], fruits [238], latex [239], tuber [240], bark [241], and cultured tissues [242], to produce nanoparticles.…”

AbstractMetal nanoparticles (MNPs) and metal oxide nanoparticles (MONPs) are used in numerous fields. The new nano-based entities are being strongly generated and incorporated into everyday personal care products, cosmetics, medicines, drug delivery, and clothing to impact industrial and manufacturing sectors, which means that nanomaterials commercialization and nano-assisted device will continuously grow. They can be prepared by many methods such as green synthesis and the conventional chemical synthesis methods. Green synthesis includes infinite accession to produce MNPs and MONPs with demanding properties. The structure–function relationships between nanomaterials and key information for life cycle evaluation lead to the production of high execution nanoscale materials that are gentle and environmentally friendly. Majority of plants have features as sustainable and renewable suppliers compared with microbes and enzymes, as they have the ability to pick up almost 75% of the light energy and transform it into chemical energy, contain chemicals like antioxidants and sugars, and play fundamental roles in the manufacture of nanoparticles. Plants considered the main factory for the green synthesis of MNPs and MONPs, and until now, different plant species have been used to study this, but the determined conditions should be taken into consideration to execute this preparation. In this study, we focus on the biosynthesis procedures to synthesize MNPs and MONPs, including comparison between green synthesis and the classical chemistry methods as well as the several new orientation of green synthesis of nanoparticles from different plant parts, especially plant leaf extracts. Plants with reducing compounds is the preferred choice for the synthesis of noble metals – metal ions can be reduced to the corresponding metals in the absence of any other chemicals under microwave irradiation conditions using benign solvent, water. Noble metals such as gold (Au), silver (Ag), platinum (Pt), and palladium (Pd) and other metals such as copper (Cu) and nickel (Ni), which are characterized by their optical, electronic, mechanical, magnetic, and chemical properties, leading to different technological applications. Plants with numerous reducing agents are suitable candidates for the manufacture of noble MNPs. The main purpose of this research is to give a background on green nanotechnology prospective evolution, pertinent concerns appeared related to the green synthesis of metal and metal oxide from plant extracts, nanoparticle formation mechanism, and the importance of flavonoids, vitamin B2, ascorbic acid (vitamin C), and phenolic compounds in the MNP and MONP production. The traditional sorghum beers are produced in many countries in Africa, but diversity in the production process may depend on the geographic localization. These beers are very rich in calories; B-group vitamins including thiamine, folic acid, riboflavin, and nicotinic acid; and essential amino acids such as lysine. However, the Western beers are more attractive than the traditional sorghum beers. The traditional sorghum beers have poor hygienic quality, organoleptic variations, and shorter shelf life compared with the Western beers. Many research studies on traditional sorghum beers have been carried out and documented in several African countries, especially the microbiological and biochemical properties, the technologies used in the manufacture processes, and synthetic characteristics of African traditional sorghum beers (ikigage, merissa, doro, dolo, pito, amgba, and tchoukoutou). The excellent resources for the production of greener biomaterials are plants and considerable advances have been achieved in many fields such as biotechnology and gene transfer. The manufactured biological nanomaterials have a great application in the pharmaceutical industry such as novel pharmaceuticals preparation, drug delivery personification procedures, and production of functional nanodevices.

Dye‐sensitized solar cells (DSSCs) have turned a new horizon in energy research due to their widespread exploration over two decades by improving efficiency, cost‐effectiveness, and easy process than inorganic‐based solar cells. The major challenges are metal complexes on designing the cells and sustainability implications for further rapid expansion due to its toxicity. To overcome the problems associated with metal complexes, the dyes are extracted from bionatural sources such as flowers, fruits, barks, petals, roots, leaves, and beans of plants. These organic dyes are being nontoxic, cost‐effective, abundant, environmentally friendly, and easy to extract, which is made them extensively applicable for DSSC. Through this review, readers may get an idea about the effect in the efficiency of the solar cell by applying variable semiconductors, effects of solvents, variable light‐harvesting pigments, types of electrolytes, and modification of counter electrodes by certain polymeric materials or nanomaterials. Furthermore, the effects of methodology, processing temperature, and pH of the medium during synthesis on solar cell parameters, such as the efficiency of DSSC, are critically analyzed which are reported by other researchers.
