“…In 2019, Du et al (2019) found that microcrystalline cellulose (MCC) and its derivatives have room temperature phosphorescence (RTP) emission and used the CTE mechanism to explain such emission behavior. These substances also exhibit aggregation-induced emission (AIE) property ( Dong et al, 2022 ).…”

The alkali mercerizing process of semicrystalline cotton fiber (CF) is widely used in the printing and dyeing industry. The crystallinity change in the mercerizing process has been studied and certain laws have been obtained, but there is still a certain distance between the theoretical research results and the practical applications. CF is almost composed of cellulose, combined with the photoluminescence (PL) phenomenon of cellulose; herein, the varying crystallinity is correlated with its PL behavior after being treated with different concentrations of NaOH. In line with the characteristics of nonconventional luminogens, CF enjoys excitation-dependent emission and persistent room temperature phosphorescence (p-RTP) behavior. The emission spectra of all samples under the same excitation wavelength indicate that the change of CF crystallinity has a significant impact on its fluorescence and p-RTP emission. As the concentration of NaOH increases, the varying trend of quantum efficiency (QY) is consistent with the changed crystallinity of CF. Interestingly, the lifetime of p-RTP is exactly the opposite of the crystallinity change law. Clustering-triggered emission (CTE), crystallization-Induced Phosphorescence (CIP) mechanism, and the swelling due to hydrated sodium ions can reasonably explain these interesting photophysical processes, which also can be supported by theoretical calculations. The above studies have basically clarified the inherent law between the crystalline change of CF and the PL emission behavior during the alkali treatment process, which can be used as a theoretical reference for real-time monitoring of CF crystallinity changes using the spectral method in the actual cotton mercerizing process.

“…Controlled sterilization using mild temperatures allows wound healing without thermal damage. A novel antibacterial nanosystem based on AuNRs, Dap@Au/Ag nanorods, can release a large amount of silver ions and antibacterial peptides (Dap) under the action of mild photothermal heating and hydrogen peroxide, which destroys the integrity of bacterial membranes and leads to death of bacteria [ 127 ]. The mild PTT achieved by this method effectively reduced the incidence of skin burns and successfully avoided secondary infections caused by burns.…”

Gold nanorods (AuNRs) are ideal inorganic nanophotothermal agents with unique characteristics, including local surface plasmon resonance effects, easy scale preparation and functional modification, and good biocompatibility. This review summarizes several recent advances in AuNRs-based photothermal therapy (PTT) research. Functionalized AuNRs photothermal agents have optimized biocompatibility and targeting properties. The multifunctional AuNRs nanoplatform composite structure meets the requirements for synergistic effects of PTT, photoacoustic imaging, and other therapeutic methods. Photothermal therapy with AuNRs (AuNRs-PTT) is widely used to treat tumors and inflammatory diseases; its tumor-targeting, tumor metastasis inhibition, and photothermal tumor ablation abilities have remarkable curative effects. An in-depth study of AuNRs in living systems and the interactions between biological structure, nanomaterial, and near-infrared irradiation could lay the foundation for further clinical research and the broad application of AuNRs in PTT.

“…2.4.5. Dap@Au/Ag Nanorods Dong et al show that a nanometric antimicrobial system Dap@Au/Ag nanorods (Dap@Au/Ag NRs), consisting of daptomycin bound to silver-coated gold nanorods, is effective against MRSA [48]. In vitro and in vivo models showed that after exposure to a laser at 808 nm, 0.8 W/cm 2 , 40-60 s, Dap@Au/Ag NRs increased its antibacterial activity with a good photothermal effect.…”

Role of Daptomycin in Cutaneous Wound Healing: A Narrative Review

et al. 2022

Daptomycin is active against Gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA) and the on-label indications for its use include complicated skin and skin structure infections (cSSSI). We performed a narrative review of the literature with the aim to evaluate the role of daptomycin in the skin wound healing process, proposing our point of view on the possible association with other molecules that could improve the skin healing process. Daptomycin may improve wound healing in MRSA-infected burns, surgical wounds, and diabetic feet, but further studies in humans with histological examination are needed. In the future, the combination of daptomycin with other molecules with synergistic action, such as vitamin E and derivates, IB-367, RNA III-inhibiting peptide (RIP), and palladium nanoflowers, may help to improve wound healing and overcome forms of antibiotic resistance.
