Abstract
The current traditional treatment for bacterial infections is to treat them with antibiotics, and the misuse of antibiotics can lead to an increase in bacterial resistance. In contrast, the development of new antibiotics is much slower than the speed of adaptation of drug-resistant bacteria, making it necessary to develop a drug that does not rely on antibiotics. Therefore, based on the advantages of photothermal therapy, NIR II-responsive gold hollow nanorods (GHNRs) were developed to overcome the limitation of bacterial drug resistance in conventional bacterial therapy. GHNRs can quickly respond to a 980 nm laser with a high photothermal conversion efficiency of 41.78%. The high temperature produced by GHNRs can effectively kill Staphylococcus aureus and Escherichia coli, providing a new strategy for the clinical treatment of bacterial infectious diseases without antibiotic dependence.
期刊介绍：
Langmuir is an interdisciplinary journal publishing articles in the following subject categories:
Colloids: surfactants and self-assembly, dispersions, emulsions, foams
Interfaces: adsorption, reactions, films, forces
Biological Interfaces: biocolloids, biomolecular and biomimetic materials
Materials: nano- and mesostructured materials, polymers, gels, liquid crystals
Electrochemistry: interfacial charge transfer, charge transport, electrocatalysis, electrokinetic phenomena, bioelectrochemistry
Devices and Applications: sensors, fluidics, patterning, catalysis, photonic crystals
However, when high-impact, original work is submitted that does not fit within the above categories, decisions to accept or decline such papers will be based on one criteria: What Would Irving Do?
Langmuir ranks #2 in citations out of 136 journals in the category of Physical Chemistry with 113,157 total citations. The journal received an Impact Factor of 4.384*.
This journal is also indexed in the categories of Materials Science (ranked #1) and Multidisciplinary Chemistry (ranked #5).
