“…The key advantages come from their biocompatibility, low toxicity, simple functionalization, and encapsulation strategies with organic molecules. Microporous inorganic structures with an extremely narrow pore size range of 0.5–2 nm ( Dou et al, 2021 ) serve as an excellent platform for adsorption and ion-exchange processes inside cells. The uptake process triggers the interactions of microporous and mesoporous NPs with bacteria.…”

Nanoantibiotics: Functions and Properties at the Nanoscale to Combat Antibiotic Resistance

One primary mechanism for bacteria developing resistance is frequent exposure to antibiotics. Nanoantibiotics (nAbts) is one of the strategies being explored to counteract the surge of antibiotic resistant bacteria. nAbts are antibiotic molecules encapsulated with engineered nanoparticles (NPs) or artificially synthesized pure antibiotics with a size range of ≤100 nm in at least one dimension. NPs may restore drug efficacy because of their nanoscale functionalities. As carriers and delivery agents, nAbts can reach target sites inside a bacterium by crossing the cell membrane, interfering with cellular components, and damaging metabolic machinery. Nanoscale systems deliver antibiotics at enormous particle number concentrations. The unique size-, shape-, and composition-related properties of nAbts pose multiple simultaneous assaults on bacteria. Resistance of bacteria toward diverse nanoscale conjugates is considerably slower because NPs generate non-biological adverse effects. NPs physically break down bacteria and interfere with critical molecules used in bacterial processes. Genetic mutations from abiotic assault exerted by nAbts are less probable. This paper discusses how to exploit the fundamental physical and chemical properties of NPs to restore the efficacy of conventional antibiotics. We first described the concept of nAbts and explained their importance. We then summarized the critical physicochemical properties of nAbts that can be utilized in manufacturing and designing various nAbts types. nAbts epitomize a potential Trojan horse strategy to circumvent antibiotic resistance mechanisms. The availability of diverse types and multiple targets of nAbts is increasing due to advances in nanotechnology. Studying nanoscale functions and properties may provide an understanding in preventing future outbreaks caused by antibiotic resistance and in developing successful nAbts.

“…MOFs are typically produced by solution mixture from room temperature to 250 °C at ambient pressure, with reaction time from a couple of minutes to several days. Due to the presence of the organic and inorganic moieties in their frameworks, they were extensively investigated in several technological applications such as gas adsorption and separation [ 57 – 59 ], electrocatalysis [ 17 – 19 , 60 , 61 ], chemical sensing [ 62 – 64 ], biomedical applications [ 64 , 65 ], and proton conduction [ 66 , 67 ]. Importantly, owing to the presence of the organic and inorganic counterparts in their composition, MOFs present numerous application chances in catalysis.…”

The core reactions for fuel cells, rechargeable metal–air batteries, and hydrogen fuel production are the oxygen reduction reaction (ORR), oxygen evolution reaction (OER), and hydrogen evolution reaction (HER), which are heavily dependent on the efficiency of electrocatalysts. Enormous attempts have previously been devoted in non-noble electrocatalysts born out of metal–organic frameworks (MOFs) for ORR, OER, and HER applications, due to the following advantageous reasons: (i) The significant porosity eases the electrolyte diffusion; (ii) the supreme catalyst–electrolyte contact area enhances the diffusion efficiency; and (iii) the electronic conductivity can be extensively increased owing to the unique construction block subunits for MOFs-derived electrocatalysis. Herein, the recent progress of MOFs-derived electrocatalysts including synthesis protocols, design engineering, DFT calculations roles, and energy applications is discussed and reviewed. It can be concluded that the elevated ORR, OER, and HER performances are attributed to an advantageously well-designed high-porosity structure, significant surface area, and plentiful active centers. Furthermore, the perspectives of MOF-derived electrocatalysts for the ORR, OER, and HER are presented.

“…3 Furthermore, the superior performance of HPPs can also come from other characteristics such as highenergy bonds (e.g., C F and C N), backbone rigidity, crosslinking networks, crystallinity, and van der Waals forces. 3,6,7 Research of the first HPPs began roughly around the 1950s and quickly expanded from thereon into the 1970s. 8 Their rapid development was mainly driven by the large demand for cost-effective materials with high strength-to-weight ratio, with the goal of enabling the advancement of industries such as transportation, aerospace engineering, and national defense.…”

“…What distinguishes HPPs from conventional engineering plastics is their superior bonds that cannot be broken easily, owing to the resonance‐stabilized aromatic groups and heterocyclic structures within the polymer backbones 3 .
