This study investigates Mn1−xXxB (X = Fe, Co) and (Fe1−xCox)2B nanoparticles as candidates for self-controlled magnetic hyperthermia (SCMH) in cancer therapy. Using a microscopic model and Green’s function techniques, we calculate the Curie temperature, saturation magnetization, coercivity, and specific absorption rate as functions of nanoparticle size and dopant concentration. Surface and size effects are taken into account. The results are in good agreement with experimental data, confirming the model’s validity and highlighting the potential of these nanoparticles for efficient and safe magnetic hyperthermia applications. We have found that pure and doped MnB and Co2B nanoparticles with specific compositions meet biocompatibility requirements for SCMH suitable for in vivo and in vitro, for example, Mn0.6Co0.4B (d = 27.1 nm); Mn0.5Co0.5B (d = 32.2 nm); MnB (d = 26.3 m); (Fe0.2Co0.8)2B (d = 22.0 nm); (Fe0.1Co0.9)2B (d = 26.3 nm); and Co2B (d = 31.7 nm).

Cancer remains one of the leading causes of death worldwide. Therefore, the continuous development of effective therapeutic strategies is necessary. Conventional anticancer chemotherapy has low bioavailability and poor systemic distribution, resulting in serious side effects and limited therapeutic efficacy. To address these limitations, drug delivery systems that respond to external stimuli have been developed to release drugs at specific sites. In this study, a phase transition-based bubble-mediated emulsion system was developed to enable near-infrared (NIR)-induced drug release. This system consists of an oil phase, 2H,3H-perfluoropentane (PFC), a fluorinated liquid gas that evaporates at a certain temperature, and encapsulated IR-780 and paclitaxel to maintain stable microbubbles. Under NIR irradiation, IR-780 exhibits a photothermal conversion effect, which increases the temperature. Above the critical temperature, PFC undergoes a phase transition into gas, forming gas bubbles. This phase transition leads to a rapid volume expansion, destroys the microbubble structure, and triggers drug release. The NIR-responsive microbubble system developed in this study facilitated targeted and selective drug release through precise temperature control using the photothermal effects and phase transition. This system provides a novel platform to improve the efficacy of cancer therapies. Full article

Continuous human population growth, industrialization, and technical progress have increased the demand for a new design and synthesis of chemical compounds. Developing eco-friendly chemical compounds has been a priority for fostering a sustainable and healthy environment, which is directly linked to human well-being. In this context, green chemistry and circular economy principles have been applied to generate valuable new chemicals, such as surfactants, with high market value. Surfactants play a crucial role in various products for both domestic and industrial applications, leading to their large-scale production a diverse array of chemical structures. However, the advantages of their use must be balanced against their negative environmental impact as pollutants. Thus, there is an increasing demand for the development of new eco-friendly surfactants. Additionally, life cycle assessment (LCA) studies of new surfactants are essential for evaluating their environmental impact, enhancing energy efficiency and facilitating the transition toward sustainable energy resources. In this work, we present the chemical synthesis of oligomeric and polymeric thiophene-based surfactants with potential applications in biosensors, organic transistors, and various other fields. The newly synthesized oligomeric and polymeric thiophene-based surfactants demonstrated medium-to-high biodegradation potential and showed no significant ecotoxicological effects on bacterial communities. However, the LCA of their synthesis revealed a negative impact on the environment and human health, particularly concerning polymeric thiophene-based surfactants. The LCA identified specific chemical steps that could be optimized to develop a new generation of eco-friendly surfactants. Full article

Iron oxide nanoparticles were synthesized using a vortex microfluidic system and subsequently functionalized with a primary shell of salicylic acid, recognized for its ability to increase the stability and biocompatibility of coated materials. In the second stage, the vortex platform was placed in a magnetic field to facilitate the growth and development of a porous silica shell. The selected drug for this study was micafungin, an antifungal agent well regarded for its effectiveness in combating fungal infections and identified as a priority compound by the World Health Organization (WHO). The resulting nanocomposite system was characterized using various techniques, including Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), dynamic light scattering (DLS), Brunauer–Emmett–Teller (BET) analysis, UV-Vis spectroscopy, and Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS). The synthesis method produced nanoparticles with dimensions of 5–7 nm, highlighting the advantages of the chosen approach. A desorption profile was established using a continuous-flow, UV-Vis analysis system, indicating that the bioactive compound was released slowly; after two hours, approximately 50% of the loaded micafungin was detected in the release medium. Furthermore, the results obtained from the FT-ICR MS analysis provided molecular-level confirmation, thereby supporting the release mechanism of micafungin from the nanosystem. Full article
