“…Sonochemical method is a non conventional and efficient route of fabricating, functionalizing, and doping iron oxide nanoparticles [1] , [2] , [3] , [4] . In addition, it has been used to synthesize other nanomaterials which include gold [5] , silver [6] , and platinum [7] . The process generates several unique conditions such as acoustic cavitation process with temperature, pressure, and cooling rate of 5000 K, 2000 atm, and 10 10 K/S, respectively.…”

“…Jameel et al synthesized highly stable, biocompatible, and ultrasmall Pt-NPs with a mean diameter of 3.8 nm using a one-step, one-pot, eco-friendly, and simple process [61]. They used an extract from Prosopis farcta fruits as a reducing agent and stabilizer and obtained an X-ray attenuation efficiency of 6.6 HU/mM at 80 kVp, higher than that of the commercial iodine contrast agent Omnipaque (3.1 HU/mM).…”

X-ray computed tomography (CT) contrast agents offer extremely valuable tools and techniques in diagnostics via contrast enhancements. Heavy metal-based nanoparticles (NPs) can provide high contrast in CT images due to the high density of heavy metal atoms with high X-ray attenuation coefficients that exceed that of iodine (I), which is currently used in hydrophilic organic CT contrast agents. Nontoxicity and colloidal stability are vital characteristics in designing heavy metal-based NPs as CT contrast agents. In addition, a small particle size is desirable for in vivo renal excretion. In vitro phantom imaging studies have been performed to obtain X-ray attenuation efficiency, which is a critical parameter for CT contrast agents, and the imaging performance of CT contrast agents has been demonstrated via in vivo experiments. In this review, we focus on the in vitro and in vivo studies of various heavy metal-based NPs in pure metallic or chemical forms, including Au, Pt, Pd, Ag, Ce, Gd, Dy, Ho, Yb, Ta, W, and Bi, and provide an outlook on their use as high-performance CT contrast agents.

“…Despite of the fact that precise control on size, morphology and even crystallinity of the MNSs have been achieved using synthetic approaches, [3,4] still their precisely controlled synthesis by sustainable and green methods are challenging. Such green‐approaches as plant extracts, [2,5] microorganisms, [6] benign organic compounds [7,8] and physical methods [9] have been proposed to improve the sustainable MNSs production. Particularly, plant extracts provide synthesis of unique shaped and sized MNSs [10–12] .…”

We performed a comparative study using aqueous extracts of dandelion flowers and blueberry fruits to synthesize gold‐ (Au) and silver‐ (Ag) nanostructures (NSs). The blueberry extracts gave nanowire and spherical AuNSs upon changing the ratio of the extracts to Au3+precursor while altering the ratio for the dandelion extracts resulted in formation of only anisotropic AuNSs. Similar results were obtained during the AgNSs, where the dandelion extracts resulted in formation of quasi‐spherical AgNSs at the tested ratio (extract/AgNO3 ratio) while altering the ratio for the blueberry extracts resulted in nanorod and nanoplates formation. We argued that this could be from dominancy of a lone compound or a group of compounds and tested this claim by introducing chrysin and amino acid mixtures to the blueberry extracts. Altering the added chrysin amount triggered nanoplate and spherical AuNSs formation while alteration in amino acid mixture content did not change the morphology, and spherical AuNSs were obtained. The antibacterial studies revealed the AgNSs are toxic to Pseudomonas aeruginosa with 8 μg/mL MBC (minimum bactericidal concentration) and 3 μg/mL values for the blueberry and dandelion extracts synthesized AgNSs while penicillin/streptomycin sulfate mixture carrying Dandelion‐AuNSs gave 12‐times lower MBC value in comparison to free penicillin/streptomycin sulfate mixture.
