Recently, photothermal therapy (PTT) has emerged as one of the most promising biomedical strategies for different areas in the biomedical field owing to its superior advantages, such as being noninvasive, target-specific and having fewer side effects. Graphene-based hydrogels (GGels), which have excellent mechanical and optical properties, high light-to-heat conversion efficiency and good biocompatibility, have been intensively exploited as potential photothermal conversion materials. This comprehensive review summarizes the current development of graphene-integrated hydrogel composites and their application in photothermal biomedicine. The latest advances in the synthesis strategies, unique properties and potential applications of photothermal-responsive GGel nanocomposites in biomedical fields are introduced in detail. This review aims to provide a better understanding of the current progress in GGel material fabrication, photothermal properties and potential PTT-based biomedical applications, thereby aiding in more research efforts to facilitate the further advancement of photothermal biomedicine.

Bandgap Semiconductors

Noble metal (NM)-modified wide-bandgap semiconductors with activity under visible light (Vis) irradiation, due to localized surface plasmon resonance (LSPR), known as plasmonic photocatalysts, have been intensively studied over the last few years. Despite the novelty of the topic, a large number of reports have already been published, discussing the optimal properties, synthesis methods and mechanism clarification. It has been proposed that both efficient light harvesting and charge carriers’ migration are detrimental for high and stable activity under Vis irradiation. Accordingly, photonic crystals (PCs) with photonic bandgap (PBG) and slow photon effects seem to be highly attractive for efficient use of incident photons. Therefore, the study on PCs-based plasmonic photocatalysts has been conducted, mainly on titania inverse opal (IO) modified with nanoparticles (NPs) of NM. Although, the research is quite new and only several reports have been published, it might be concluded that the matching between LSPR and PBG (especially at red edge) by tuning of NMNPs size and IO-void diameter, respectively, is the most crucial for the photocatalytic activity.

Iron oxide magnetic nanomaterials are among the most widely used nanomaterials in nanomedicine. Due to their magnetic and structural properties, iron oxide magnetic nanotubes are extremely attractive for biomedical applications. This paper presents the synthesis of iron oxide magnetic nanotubes, and their potential applications in drug delivery. Three types of iron oxide magnetic nanotubes, i.e., hematite, maghemite, and magnetite, were synthesized using template and hydrothermal methods, and the effects of synthesis methods on the morphological and crystalline properties of the synthesized magnetic nanotubes were analyzed. The magnetization properties of the three types of synthesized magnetic nanotubes and their responses to external magnetic fields were studied. To explore their applications in drug delivery, the drug loading and release capabilities of the synthesized magnetic nanotubes were investigated. The final part of this paper discusses several important issues related to the applications of iron oxide magnetic nanotubes for drug delivery, especially the controlled release of drugs.
