Antifungal Agents

Antifungal Agents

Amphotericin B is a broad-spectrum antifungal agent that exploits structural differences between fungal and mammalian cell membranes. Its amphipathic structure—featuring a hydrophobic polyene-lactone ring and a hydrophilic region containing mycosamine and carboxylic acid groups—enables selective binding to ergosterol, a sterol predominantly found in fungal plasma membranes. This selective interaction underlies the drug’s antifungal activity, although weak binding to cholesterol contributes to...

Background:

Effective electromagnetic wave absorption (EMWA) and broad effective absorption bandwidth (EAB) are crucial for advanced materials.
Structural design and interface regulation are key strategies to enhance EMWA properties.

Purpose of the Study:

To develop a novel, high-performance EMWA material with a biomimetic design.
To investigate the synergistic dielectric-magnetic properties of the fabricated composite for optimized EM wave attenuation.

Main Methods:

Fabrication of a raspberry-like absorbent using a monomer-mediated strategy for covalent organic framework (COF) wrapping of Gd-doped FeNi3 (GFN) nanoparticles.
Construction of a dielectric-magnetic synergistic system with COF-derived nitrogen-doped porous carbon (NPC) shell and GFN core.
Tuning electromagnetic parameters by adjusting GFN and NPC proportions and utilizing off-axis electron holography to analyze EM wave loss mechanisms.

Main Results:

The GFN@NPC composites exhibited tunable electromagnetic parameters and broad EMWA performance.
An effective absorption bandwidth (EAB) up to 6.0 GHz was achieved for all composites.
The GFN@NPC-2 sample showed a minimum reflection loss (RLmin) of -69.6 dB and a maximum radar cross-section (RCS) reduction of 29.75 dB·m².
A multi-layer gradient structure achieved an ultra-wide EAB of 12.24 GHz through metamaterial simulation.

Conclusions:

The study presents a novel bio-inspired design strategy for high-performance EMWA materials.
The fabricated GFN@NPC composites demonstrate significant potential for electromagnetic wave absorption applications.
Interface polarization and microscale magnetic interactions play a critical role in the EM wave loss mechanism.
