Abstract
Abstract With the prevalence of antibiotic-resistant bacteria, novel antibacterial strategies are urgently needed. In recent years, several antibiotics-independent physical approaches have attracted high attention and interests. Among those approaches, photothermal therapy (PTT), a novel non-invasive therapeutic technique, has exhibited great potentials in dealing with drug-resistant bacteria and bacterial biofilms. Photothermal agents (PTAs), which are either nanomaterials themselves or small molecules loaded in nanoparticles, are the essential element for PTT. How to deliver PTAs in a controlled manner is of great importance for high-efficiency and low-toxicity PTT. Therefore, a comprehensive understanding of various PTAs is required for the better application of PTT in antibacterial treatment. Herein, the physicochemical properties and antibacterial PTT of five types of PTAs are summarized. In addition, the PTT-involved multifunctional theranostics nanoplatforms and the potential approaches for reducing the side effects of PTT (such as targeted delivery and controlled release of PTAs) are also discussed.

Abstract Treatment of oral pathogens is important for both oral and systemic health. The antimicrobial activity of chitosan (CS)-based scaffolds either loading antibiotics or compositing with other agents are well documented. However, the intrinsic antibacterial activity of CS scaffolds alone has never been reported. Herein, we fabricated the non-crosslinked CS scaffold and investigated its antibacterial activity against typical oral pathogens, Gram-negative Porphyromonas gingivalis and Gram-pos...

Abstract The antibiotics-independent antimicrobial activity of graphene oxide (GO) is of great importance since antibiotic therapy is facing great challenges from drug resistance. However, the relations of GO size with its antimicrobial activity and how the size regulates the antibacterial mechanisms are still unknown. Herein, we fabricated four GO suspensions with different sizes and demonstrated the parabolic relationship between GO size and its antibacterial activity against the Gram-positive...

Second near-infrared window (NIR-II, 1000-1700 nm) absorption or fluorescent agents have attracted great attention due to that it can overcome the penetration limitation of first near-infrared window (NIR-I, 750–1000 nm). However, these always “on” agents face the severe problem that they are susceptible to retention and phagocytosis by the reticuloendothelial system after intravenous administration, which will produce signal interference during diagnosis and side effects during treatment. Tumor...

Abstract With the emergence of drug-resistant bacteria, conventional antibiotics are becoming increasingly ineffective for the treatment of bacterial infections. Nanomaterial-modified antibiotics, denoted as “nanoantibiotics”, can usually circumvent most of the shortcomings of conventional antibiotics, thus improving antibacterial activities. Here, we developed triclosan-based supramolecular hydrogel nanoantibiotics by conjugating small molecule antibiotic triclosan (TCS) to self-assembling pept...

Abstract The rapid dissemination of life-threatening multidrug-resistant bacterial pathogens calls for the development of new antibacterial agents and alternative strategies. The virulence factor secreted by bacteria plays a crucial role in the sophisticated processes during infections. Inspired by the unique capacity of many bacteria inducing clotting of plasma to initiate colonization, we propose a programmable antibiotic delivery system for precision therapy using methicillin-resistant S. aur...

Abstract Ag@Au core-shell structure nanoparticles, integrating the good stability of Au and the high surface plasmon resonance property (LSPR) of Ag have been extensively employed for photothermal therapy. Up to now, their sophisticated synthesis still remains a great challenge due to the galvanic replacement effect. Herein, through introduction of Ag, we demonstrated that the Ag@Au core-shell nanoplates were easily synthesized in a galvanic replacement-free fashion with no compromise of heating...

Abstract In most cases, once nanoparticles (NPs) enter the blood, their surface is covered by biological molecules, especially proteins, forming a so-called protein corona (PC). As a result, what the cells of the body “see” is not the NPs as formulated by the chemists, but the PC. In this way, the PC can influence the effects of the NPs and even mask the desired effects of the NP components. While this can argue for trying to inhibit protein-nanomaterial interactions, encapsulating NPs in an end...

Staphylococcus aureus (S. aureus) related staphylococcal infection is one of the most common types of hospital-acquired infections, which requires selective and effective treatment in clinical practice. Considering gelatinase as a characteristic feature of S. aureus, gelatinase-responsive release of the antibiotic reagent thereby can target the pathogenic S. aureus while sparing beneficial bacteria in the microflora. In this work, we design a hybrid antibacterial photodynamic peptide (APP, Ce6-G...

Increasing evidence suggested that bacterial infection diseases posed a great threat to human health and became the leading cause of mortality. However, the abuse of antibiotics and their residues in the environment result in the emergence and prevalence of drug-resistant bacteria. Photothermal therapy (PTT) has received considerable attention owing to its noninvasiveness, and proved to be promising in preventing bacterial infection diseases. In this review, we first surveyed the recent progress...
