“…Comparison between the obtained results to the reduction of 4-NP in the presence of HAP/MIL-101(Fe)/Ag/Fe 3 O 4 catalyst and NaBH 4 with other reported catalysts is indicated in Table 1. 39–52 From Table 1, it can be seen that the reaction in the presence of the HAP/MIL-101(Fe)/Ag/Fe 3 O 4 catalyst required a shorter reaction time compared with most of the reported catalysts, which confirms the potential of the current catalyst for the reduction of 4-nitrophenol in aqueous solutions.…”

“…The loaded folic acid nanoparticles presented with peaks at 38°, 45°, 65°, and 80° It established folic acid's crystalline form and demonstrated its effective fusion with the other components of the BPENP. XRD patterns for the pollencoated AuNPs samples showed four distinctive diffraction peaks at 2θ (38.14°, 44.41°, 64.75°, and 77.78°), as described byKumar et al, 2022) [35].…”

Bee pollen extract (BPE)-based polymer nanoparticles (BPENP) were fabricated by using bovine serum albumin (BSA) and targeted with folic acid and were further characterized. Mice groups are : Group 1 received saline, whereas Groups 2, 3, 4, 5, and 6 received a single dose of urethane, followed by weekly injections of butylated hydroxy-toluene (BHT). After the BHT injection, the mice in Groups 3, 4, 5, and 6 received BPE, Avastin,BPENP, and BNENP + Avastin, respectively. The number and size of tumors decreased in Group 6 compared to those in the other groups. The ratios of early and late apoptotic cells in Groups 3, 4, 5, and 6 (42.8%, 41.4%, 26.2%, and 45.4%, respectively) were lower than that in the untreated group. The PCNA-labeling indices (LI)% in tissues and lesions from Group 6 were lower than those in the other groups; on the other hand, the caspase 3 LI (%) was higher than those in the other groups. No significant differences in HRAS and MAPK levels were observed between Group 6 and the other groups. However, the level of Baxwas significantly increased, whereas those of Bcl2 and P21 were decreased in Group 6 compared to those in Groups 4 and 5.

“…These properties make them useful in the treatment of cancer, cardiovascular diseases, ischemic diseases, wound healing, and other conditions. In order to create gold nanoparticles in an environmentally friendly manner, Kumar et al [ 83 ] investigated their catalytic reduction of 4-nitrophenol using an Andean bee pollen water extract. The findings of the experiments demonstrated that Au NPs could efficiently convert the organic pollutant 4-NP into 4-aminophenol.…”

Because of their small size and large specific surface area, nanoparticles (NPs) have special properties that are different from bulk materials. In particular, Au/Ag NPs have been intensively studied for a long time, especially for biomedical applications. Thereafter, they played a significant role in the fields of biology, medical testing, optical imaging, energy and catalysis, MRI contrast agents, tumor diagnosis and treatment, environmental protection, and so on. When synthesizing Au/Ag NPs, the laser ablation and biosynthesis methods are very promising green processes. Therefore, this review focuses on the progress in the laser ablation and biological synthesis processes for Au/Ag NP generation, especially in their fabrication fundamentals and potential applications. First, the fundamentals of the laser ablation method are critically reviewed, including the laser ablation mechanism for Au/Ag NPs and the controlling of their size and shape during fabrication using laser ablation. Second, the fundamentals of the biological method are comprehensively discussed, involving the synthesis principle and the process of controlling the size and shape and preparing Au/Ag NPs using biological methods. Third, the applications in biology, tumor diagnosis and treatment, and other fields are reviewed to demonstrate the potential value of Au/Ag NPs. Finally, a discussion surrounding three aspects (similarity, individuality, and complementarity) of the two green synthesis processes is presented, and the necessary outlook, including the current limitations and challenges, is suggested, which provides a reference for the low-cost and sustainable production of Au/Ag NPs in the future.
