Palladium nanoparticles (PdNPs) have intrinsic features, such as brilliant catalytic, electronic, physical, mechanical, and optical properties, as well as diversity in shape and size. The initial researches proved that PdNPs have impressive potential for the development of novel photothermal agents, photoacoustic agents, antimicrobial/antitumor agents, gene/drug carriers, prodrug activators, and biosensors. However, very few studies have taken the benefit of the unique characteristics of PdNPs for applications in the biomedical field in comparison with other metals like gold, silver, or iron. Thus, this review aims to highlight the potential applications in the biomedical field of PdNPs. From that, the review provides the perceptual vision for the future development of PdNPs in this field.

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.

This review article describes the synthesis, properties and some applications of star-shaped polymers. The arms constituted of homo- or co-polymers of different polymers are also reviewed. Methods of synthesis of various types of star-shaped polymers, including “arm first” and “core first” procedures,  is given as an introduction along with some details. Then, the synthesis of star polymers (including miktoarm stars) with strictly defined as well as with varying number of arms and having cores formed from small and/or large molecules: branched, cross-linked, etc., is described. Interest in star-shaped and branched systems based on poly (ethylene oxide) (PEO) is mainly motivated by their potential applications in the biomedical and pharmaceutical areas. The properties and applications of PEO stars are also reported, such as drug carriers, surface modifiers, hydrogels, components of membranes, and also have some biomedical applications. Their potential applications as components of different types of complexes, hydrogels, networks, and ultrathin coatings are indicated.

Current research is a computational study in which we focus on calculating optical properties of Eu-doped Cadmium Sulfide (CdS) system. We employ Perdew–Burke–Ernzerhof (PBE)–generalized gradient approximation (GGA) for accomplishment of our study and we assume various Eu concentrations (3.12%, 6.25% and 9.37%) for doping into host CdS lattice. We substitute Cd atoms with Eu atoms while supercell size is kept fixed ([Formula: see text]. We present a detailed comparison among optical properties of pure CdS and various Eu concentrations. Partial density of states (PDOS) plots reveal hybridization among Cd [Formula: see text]-states, S [Formula: see text]-states and Eu [Formula: see text]-states and because of it, material (CdS:Eu) shows exceptional energy transfer which influences optical spectra and electronic properties. A considerable change in absorption spectra is noted, where in comparison to pure CdS, absorption shows blueshift with increasing Eu concentrations. Our DFT results were found to have great resemblance with existing literature. Addition of Eu into the CdS lattice originates novelty in CdS:Eu system and number of potential applications related to the field of biomedical physics, amperometric biosensors, quantum dots (QDs) sensors, photonics, bioprinting, biosensing luminophores, solar cells and optoelectronics industry may be explored in technological perspectives.

In recent years, polymer nanocomposites produced by combining nanofillers and a polymeric matrix are emerging as interesting materials. Polymeric composites have a wide range of applications due to the outstanding and enhanced properties that are obtained thanks to the introduction of nanoparticles. Therefore, understanding the filler-matrix relationship is an important factor in the continued growth of this scientific area and the development of new materials with desired properties and specific applications. Due to their performance in response to a magnetic field magnetic nanocomposites represent an important class of functional nanocomposites. Due to their properties, magnetic nanocomposites have found numerous applications in biomedical applications such as drug delivery, theranostics, etc. This article aims to provide an overview of the filler-polymeric matrix relationship, with a special focus on magnetic nanocomposites and their potential applications in the biomedical field.

Cell Adhesion And Proliferation

A comparative analysis concerning bio-based gels production, to be used for tissue regeneration, has been performed in this review. These gels are generally applied as scaffolds in the biomedical field, thanks to their morphology, low cytotoxicity, and high biocompatibility. Focusing on the time interval 2015–2020, the production of 3D scaffolds of alginate, chitosan and agarose, for skin and bone regeneration, has mainly been investigated. Traditional techniques are critically reviewed to understand their limitations and how supercritical CO2-assisted processes could overcome these drawbacks. In particular, even if freeze-drying represents the most widespread drying technique used to produce polysaccharide-based cryogels, supercritical CO2-assisted drying effectively allows preservation of the nanoporous aerogel structure and removes the organic solvent used for gel preparation. These characteristics are essential for cell adhesion and proliferation.
