“…However, the critical reason for applying SERS technology in on-site clinics is to overcome the limitations of conventional in vitro diagnostic procedures (such as fluorescence or luminescence). 35–38 Hence, the clinical data measured using existing clinical diagnostic methods must be analyzed and compared with those measured using SERS detection methods to validate this hypothesis. Therefore, this review focuses on recent research trends in label-based detection.…”

The misuse of antibiotics has led to increased bacterial resistance, posing a global public health crisis and seriously endangering lives. Currently, antibiotic therapy remains the most common approach for treating bacterial infections, but its effectiveness against multidrug‐resistant bacteria is diminishing due to the slow development of new antibiotics and the increase of bacterial drug resistance. Consequently, developing new a\ntimicrobial strategies and improving antibiotic efficacy to combat bacterial infection has become an urgent priority. The emergence of nanotechnology has revolutionized the traditional antibiotic treatment, presenting new opportunities for refractory bacterial infection. Here we comprehensively review the research progress in nanotechnology‐based antimicrobial drug delivery and highlight diverse platforms designed to target different bacterial resistance mechanisms. We also outline the use of nanotechnology in combining antibiotic therapy with other therapeutic modalities to enhance the therapeutic effectiveness of drug‐resistant bacterial infections. These innovative therapeutic strategies have the potential to enhance bacterial susceptibility and overcome bacterial resistance. Finally, the challenges and prospects for the application of nanomaterial‐based antimicrobial strategies in combating bacterial resistance are discussed.This article is categorized under: Biology‐Inspired Nanomaterials > Nucleic Acid‐Based Structures Therapeutic Approaches and Drug Discovery > Nanomedicine for Infectious Disease

Gold nanoparticles (AuNPs), universally regarded as colorimetric signal reporters, are widely employed in lateral flow immunoassays (LFIAs). However, it is difficult for AuNPs‐LFIA to achieve a wide range and sensitive detection. Herein, novel coral‐like hollow gold nanospheres (CHGNPs) are synthesized. The growth of gold nanospheres can be regulated to obtain a multibranched and hollow construction. The obtained CHGNPs possess intense broadband absorption across the visible to near‐infrared region, exhibiting a high molar extinction coefficient of 14.65 × 1011 M−1 cm−1 and a photothermal conversion efficiency of 79.75%. Thus, the photothermal/colorimetric dual‐readout LFIA is developed based on CHGNPs (CHGNPs‐PT‐LFIA and CHGNPs‐CM‐LFIA) to effectively improve the detection sensitivity and broaden the detection range in regard to sulfonamides (SAs). The limits of detection of the CHGNPs‐PT‐LFIA and CHGNPs‐CM‐LFIA reached 1.9 and 2.8 pg mL−1 for the quantitative detection of sulfaquinoxaline, respectively, which are 6.3‐fold and 4.3‐fold lower than that of the AuNPs‐LFIA. Meanwhile, the CHGNPs‐PT‐LFIA broadened the detection range to three orders of magnitude, which ranged from 2.5 to 5000 pg mL−1. The synthesized photothermal CHGNPs have been proven effective in improving the performance of the LFIA and provide a potential option for the construction of sensing platforms.
