Hierarchical‐Bioinspired MOFs Enhanced Electromagnetic Wave Absorption

Abstract

Proteins exhibit complex and diverse multi‐dimensional structures, along with a wide range of functional groups capable of binding metal ions. By harnessing the unique characteristics of proteins, it is possible to enhance the synthesis of metal‐organic frameworks (MOFs) and modify their morphology. Here, the utilization of biomineralized bovine serum albumin (BSA) protein as a template for synthesizing Mil‐100 with superior microwave absorption (MA) properties is investigated. The multi‐dimensional structure and abundant functional groups of biomineralized BSA protein make it an ideal candidate for guiding the synthesis of Mil‐100 with intricate network structures. The BSA@Mil‐100 synthesized using this method exhibits exceptional uniformity and monodispersity of nanocrystals. The findings suggest that the BSA protein template significantly influences the regulation of nanocrystal and microstructure formation of Mil‐100, resulting in a highly uniform and monodisperse structure. Notably, the synthesized 2‐BSA@Mil‐100 demonstrates a high reflection loss value of −58 dB at 8.85 GHz, along with a maximum effective absorption bandwidth value of 6.79 GHz, spanning from 6.01 to 12.8 GHz. Overall, this study highlights the potential of utilizing BSA protein as a template for MOF synthesis, offering an effective strategy for the design and development of high‐performance MA materials.

MoS2-Based Nanocomposites for Microwave Absorption: A Review

“…In order to meet the needs of complex electromagnetic environments in the future, the properties of microwave absorbing materials need to be further studied. We consider several aspects of research significance as follows: It is imperative to continue to study the new absorbing loss mechanism inside MoS 2 -based absorbing materials. , Some new techniques are used to further investigate the loss mechanism inside the material at the micro level, such as electron hologram of visual magnetic resonance, density functional theory to calculate charge redistribution and conduction, and finite element analysis to evaluate the contribution of the macroscopic structure . From the micro and macro point of view, the absorption mechanisms inside and outside the material are studied and their contribution to the performance is analyzed. MoS 2 -based microwave absorbing materials need to be developed in the direction of multifunction.…”

Nature-inspired protein mineralization strategies for nanoparticle construction: advancing effective cancer therapy

“…The ampholytic and richly reactive nature and strong microwave absorption capability can potentially enhance the properties of albumin. 154 Besides, when BSA is used as a model protein to enclose metal components, it can form a protein cap by preventing the NPs from binding to proteins in the blood circulation, which endows NPs with appropriate biocompatibility and non-immunogenicity. Next, particle size, a difficult characteristic to control, is a permanent and important value in nanotechnology that influences the biodistribution, metabolic pathway, and ultimate toxicity of NPs.…”
