“…reported that by self‐assembly of CuO nanospindles into CuO nanoflowers an enhanced antimicrobial activity compared to isolated nanospindles can be achieved due to coupling effects. [ 65 ] Moreover, SPs provide an ideal platform for combining different antimicrobial nanomaterials in one disinfection agent, as recently suggested by Mauter et al. [ 20 ] The colocalization of TiO 2 , Ag, ZnO NPs, and carbon nanotubes in a single SP would yield a versatile tool with multiple pathogen inactivation pathways for efficient wide‐range pathogen deactivation.…”

The indispensable transformation to a (more) sustainable human society on this planet heavily relies on innovative technologies and advanced materials. The merits of nanoparticles (NPs) in this context are demonstrated widely during the last decades. Yet, it is believed that the impact of particle‐based nanomaterials to sustainability can be even further enhanced: taking NPs as building blocks enables the creation of more complex entities, so‐called supraparticles (SPs). Due to their evolving phenomena coupling, emergence, and colocalization, SPs enable completely new material functionalities. These new functionalities in SPs can be utilized to render six fields, essential to human life as it is conceived, more sustainable. These fields, selected based on an entropy‐rate‐related definition of sustainability, are as follows: 1) purification technologies and 2) agricultural delivery systems secure humans “fundamental needs.” 3) Energy storage and conversion, as well as 4) catalysis enable the “basic comfort.” 5) Extending materials lifetime and 6) bringing materials back in use ensure sustaining “modern life comfort.” In this review article, a perspective is provided on why and how the properties of SPs, and not simply properties of individual NPs or conventional bulk materials, may grant attractive alternative pathways in these fields.

“…For instance, Muthalagu group synthesized CuO nanospindles with the average diameter and length of 27 nm and 88 nm, respectively, first using a green method and then assembled them into nanoflowers by using Dodonaea angustifolia extract (Figure 7F). [ 147 ] In comparation with CuO nanospindles, the antibacterial ability of CuO nanoflowers with the average diameter and length of 38 nm and 97 nm, was improved. Haque et al.…”

Transition metal–based nanoparticles have attracted more and more attention in biomedicine, owing to their special characteristics that arise from finite‐size and surface effects, such as intense and broad light absorption, strong oxidation ability, catalytic activity, and robust mechanical properties. Researches on transition metal–based nanoparticles and their clinical applications have been, so far, mainly focus on the spherical shape. However, many efforts have been made to develop different anisotropic shapes to increase their physicochemical properties and biological activity. In this regard, it would be of great benefit to elaborate the recent developments, especially over the past 20 years, on the synthesis of anisotropic transition metal–based nanomaterials and their unique shape‐dependent properties, mechanism, as well as superiority and limitations in biomedicine, such as drug delivery, disease therapy, and resonance imaging. Here, we will summarize in detail the mechanism and advantages of three main shape categories of anisotropic transition metal–based nanomaterials in biomedical applications, including one‐dimensional (e.g., nanowire), two‐dimensional (e.g., nanosheet), and three‐dimensional (e.g., nanorod, nanocube, and nanoflower) anisotropic shapes. In addition, the critical challenges and prospects of this field will be also proposed and discussed.

“…The antibacterial activity of SS-Ag NPs against gram-negative bacteria was more than gram-positive bacteria due to the variations in peptidoglycan layer thickness [52]. Among the various bacterial strains, the SS-Ag NPs showed enhanced antimicrobial activity against K. pneumoniae ( figure 8b) due to the variations in cell structure, diffusion rate, metabolism and interaction of the nanoparticles with the microorganisms [53].

Biogenic synthesis of silver nanoparticles (SS-Ag NPs) using the extract of Saccharum spontaneum (SS) via green chemistry route was investigated for their in-vitro cytotoxicity on osteoblast-like cells and bactericidal effect. Synthesized SS-Ag NPs were analyzed using TEM, FTIR, XRD and UV Vis spectroscopy techniques. The biomolecules present in S. spontaneum were responsible for the reduction and capping of silver nanoparticles. A heterogenous mixture of SS-Ag NPs which consists of triangle, hexagonal, spherical and rod-like structures was obtained. Furthermore, the synthesized SS-Ag NPs were tested for in a broad spectrum of antibacterial activity against E. coli, S. aureus, K. pneumonia and P. aeruginosa and it showed significant inhibitory effect. For the first time, the enhancement in the proliferation rate of MG63 cells with SS-Ag NPs is reported.
