AI Article Synopsis
- The study focuses on a superstructure created from 50 nm gold nanoparticles (Au NPs) organized within 3D microgel networks.
- The microgel enhances the optical properties, allowing for absorption of light in the visible to near-infrared range, which is not a characteristic of the Au NPs alone.
- This system shows high photothermal efficiency and can be used to deliver photosensitive drugs, making it a potential method for combined cancer therapies involving both photothermal and photodynamic treatments.
Article Abstract
The whole is a collection of parts and fulfills specific functions that the parts do not have. In this work, 50 nm Au NPs were in situ synthesized and close packed into a superorganism-like superstructure by means of microgel 3D networks. The combined microgel is endowed with ultra-wide absorption in visible and near-infrared regions between 500 and 1100 nm in spite of Au NPs not having this property. The strong collective plasmon coupling between neighboring Au NPs induces high photothermal conversion efficiency of the microgel system under irradiation at various laser wavelengths. Due to the good loading capability, microgels with nanocomposites can also load photosensitive drugs simultaneously and be used for combined cancer treatments of photothermal therapy and photodynamic therapy.

Metasurface solar absorber serves as a kind of important component for green energy devices to convert solar electromagnetic waves into thermal energy. In this work, we design a new solar light absorber configuration that incorporates the titanium nitride substrate, aluminum oxide layer, titanium nitride layer, and the topmost refractory nanostructures. The metasurface absorber based on this configuration can achieve an average spectral absorption of over 91% and a total solar radiation absorption of 91.

Structural design and interface regulation are useful strategies for achieving strong electromagnetic wave absorption (EMWA) and broad effective absorption bandwidth (EAB). Herein, a monomer-mediated strategy is employed to control the growth of covalent organic framework (COF) wrapping flower-shaped Gd-doped FeNi (GFN), and a novel raspberry-like absorbent based on biomimetic design is fabricated by thermal catalysis. Further, a unique dielectric-magnetic synergistic system is constructed by utilizing the COF-derived nitrogen-doped porous carbon (NPC) as the shell and anisotropic GFN as the core.
