“…As a negative control, the same irradiation had little impact on PBS solution. The ΔT of the BRE solution at the concentration of 20 mg/mL was about 35.2°C, indicating the photothermal capability that matches many photothermal materials such as Pd@Au/Ce6/PAH/H-MnO 2 ( Figure 1C ; Liu et al, 2020 ). In addition, we further showed that the photothermal performance of BRE was dependent on the irradiation power density ( Figure 1D ).…”

It remains a challenge to develop an effective therapeutic agent with low cost and good biocompatibility for cancer therapy. Based on its dark color, we hypothesized that, the extraction from black rice grains, denoted BRE, could serve as a photothermal conversion agent. The results showed that BRE confers a high photothermal conversion efficiency up to 54.13%. The combination of BRE and near infrared (NIR) treatment enables effective photothermal tumor ablation, and suppress tumor metastasis via inhibiting the epithelial-mesenchymal transition (EMT) pathway. In addition, BRE exhibits no obvious toxicity in vivo. Therefore, BRE could serve as a promising photothermal therapy agent with a low toxicity to treat cancer.

“…The photothermal conversion efficiency of gallic acid-conjugated silver (GA-Ag) NPs was found to be 48.70%, which is higher than that of other nanocomposites, such as PEG-conjugated MoS 2 nanoflowers, CuS nanodots, bismuth selenide nanospherical sponges, platinum NPs, and Prussian blue nanocages [ 61 , 62 ]. As previously mentioned, photothermal conversion was higher for GA-Ag NPs than other nanocomposites, making it an effective candidate against antibiotic-resistant microbes.…”

“…The temperature due to laser irradiation reached 50.6 °C near the wound region from 36.4 °C for GA-Ag NPs, indicating effective microbial inhibition compared to their counterparts. Hematoxylin and eosin (H&E) staining showed an acute inflammatory response due to laser irradiation, and there was accelerated wound healing [ 61 ].…”

An upsurge in the multidrug-resistant (MDR) bacterial pestilence is a global cause for concern in terms of human health. Lately, nanomaterials with photothermal effects have assisted in the efficient killing of MDR bacteria, attributable to their uncommon plasmonic, photocatalytic, and structural properties. Examinations of substantial amounts of photothermally enabled nanomaterials have shown bactericidal effects in an optimized time under near-infrared (NIR) light irradiation. In this review, we have compiled recent advances in photothermally enabled nanomaterials for antibacterial activities and their mechanisms. Photothermally enabled nanomaterials are classified into three groups, including metal-, carbon-, and polymer-based nanomaterials. Based on substantial accomplishments with photothermally enabled nanomaterials, we have inferred current trends and their prospective clinical applications.

“…In nanocomposite hydrogels, the polar nanofillers (such as nano-cellulose and SiO 2 nanoparticles) act as secondary crosslinking agents and can interact strongly with hydrogel matrix to give mechanical strength to the hydrogel. [93][94][95] Other types of nanoparticles which can be used to create various properties in hydrogels include electroconductive agents (electroconductive polymers, carbon nanotubes (CNT) and graphene), [96][97][98] antibacterial nanofillers (such as nanoparticles of Ag, ZnO, and Cu), [99] and quantum dots. [100] Moreover, addition of other ingredients to the boraxbased nanocomposite hydrogels have been evaluated for the fabrication of hybrid materials.…”

Self-healing polyol/borax hydrogels have found great applications in various areas; especially in sensors, flexible electronics and biomedical fields. In this review, fabrication and characteristics of various types of borax-based hydrogels are discussed. Mechanical properties and self-healing behaviors of these hydrogels are strongly affected by the types of polyol, ratio of polyol:borax, and concentration of each component. Incorporation of highly polar nanofillers (such as cellulose nanofibers) into hydrogels and fabrication of double-network structures have been employed as the promising strategies for improving the mechanical properties. Other additives have also been examined to generate nanocomposite hydrogels for a wide variety of uses; e. g. polyphenols for developing adhesives, conducting polymers, and hybrid structures based on carbon nanotubes and graphenes for electroconductivity, Ag and ZnO nanoparticles for antibacterial property, and quantum dots for fluorescence.
