“…A comparison of the antimicrobial efficiency among some PTT and PDT drugs are also listed. Table S2 includes conditions such as antimicrobial mechanism, nanomaterial concentration and antimicrobial activity [ 27 , 33 , 34 , 65 , 66 , 67 , 68 , 69 , 70 ]. It is observed that the antibacterial properties of MXene and its composites are outstanding under similar conditions.…”

Ru(II) Complex Grafted Ti3C2Tx MXene Nano Sheet with Photothermal/Photodynamic Synergistic Antibacterial Activity

For a long time, the emergence of microbial drug resistance due to the abuse of antibiotics has greatly reduced the therapeutic effect of many existing antibiotics. This makes the development of new antimicrobial materials urgent. Light-assisted antimicrobial therapy is an alternative to antibiotic therapy due to its high antimicrobial efficiency and non-resistance. Here, we develop a nanocomposite material (Ru@MXene) which is based on Ru(bpy)(dcb)2+ connected to MXene nanosheets by ester bonding as a photothermal/photodynamic synergistic antibacterial material. The obtained Ru@MXene nanocomposites exhibit a strengthened antimicrobial capacity compared to Ru or MXene alone, which can be attributed to the higher reactive oxygen species (ROS) yield and the thermal effect. Once exposed to a xenon lamp, Ru@MXene promptly achieved almost 100% bactericidal activity against Escherichia coli (200 μg/mL) and Staphylococcus aureus (100 μg/mL). This is ascribed to its synergistic photothermal therapy (PTT) and photodynamic therapy (PDT) capabilities. Consequently, the innovative Ru@MXene can be a prospective non-drug antimicrobial therapy that avoids antibiotic resistance in practice. Notably, this high-efficiency PTT/PDT synergistic antimicrobial material by bonding Ru complexes to MXene is the first such reported model. However, the toxic effects of Ru@MXene materials need to be studied to evaluate them for further medical applications.

“…Very recently, metal ions were found to be efficient in achieving the controlled synthesis of P( l -DOPA) NPs . Compared with other synthetic strategies, such as enzymatic catalysis or strong oxidant participation, ,, this method is cheap, mild, and convenient, and thus has been favored by other researchers. − While encouraged, it cannot be ignored that metal ions are unpopular in some application areas, and metal-free approach has gradually become an eco-friendly or biofriendly trend. , Therefore, a robust and metal-free synthetic strategy is still highly desirable to make P( l -DOPA)-based melanin materials applicable to various scenarios.…”

Quaternary Ammonium Assisted Synthesis of Melanin-like Poly(l-DOPA) Nanoparticles with a Boosted Photothermal Effect

Poly(levodopa) nanoparticles (P(L-DOPA) NPs) are another kind of melanin mimetic besides well-established polydopamine nanoparticles (PDA NPs). Due to the presence of carboxyl groups, the oxidative polymerization of L-DOPA to obtain particles was not as efficient as that of dopamine. Several established methods toward P(L-DOPA) NP fabrication do not combine convenience, morphological regularity, size controllability, low cost, and adaptability to metal-free application scenarios. In this work, P(L-DOPA) NPs were successfully prepared in hot water with the assistant of organic quaternary ammonium, due to the extra physical cross-linking mediated by cations. The employed physical interactions could also be affected by quaternary ammonium structure (i.e., number of cation heads, length of alkyl chain) to achieve different polymerization acceleration effects. The obtained P(L-DOPA) NPs retained superior photothermal properties and outperformed PDA-based melanin materials. Furthermore, P(L-DOPA) NPs were used in photothermal tumor therapy and showed better efficacy. This study offers new insights into the synthesis of melanin-like materials, as well as new understanding of the interaction between quaternary ammonium and bioinspired polyphenolic materials.

Synthesized melanin nanoparticles (SMNPs) are used as advanced photothermal materials. However, their internal structures are complex and disordered, and tuning the photothermal performance of nanoparticles is still a hot spot of concern. This article presents thionin (Th)‐doped SMNPs, namely Th‐SMNPs, which are the first SMNPs formed using the one‐pot polymerization of Th with Levodopa. Th can undergo Michael addition and Schiff base reaction between indole dihydroxy/indolequinone and their oligomers to form donor–acceptor pairs in the structure to modulate the photothermal performance of SMNPs. Structural and spectroscopic analyses and density functional theory simulations further confirm the existence of the donor–acceptor structure. Th‐SMNPs exhibit excellent total photothermal efficiency (34.49%) in the near‐infrared region (808 nm), which is a 60% improvement compared to SMNPs. This allows Th‐SMNPs to exhibit excellent photothermal performance at low power 808 nm laser irradiation. Meanwhile, Th not only enhances the photothermal properties of SMNPs, but also imparts photodynamic effects to SMNPs. Th‐SMNPs can produce 1O2 under 660 nm laser irradiation. A dual‐function photothermal and photodynamic textile named Th‐SMNPs@cotton is constructed based on Th‐SMNPs, which can act as a rapid photothermal/photodynamic sterilization and is promising for wound healing treatment of bacterial infections under low‐power dual laser irradiation.
