Photodynamic therapy (PDT) is a promising, effective, and non‐invasive treatment for superficial cancers, utilizing reactive oxygen species (ROS) generated by induced light‐irradiated photosensitizers (PS) to provoke cancer cell death. Photothermal therapy (PTT) on the other hand, relies on heat generation by light‐irradiated PS for effective thermal cancer treatment. Both treatments have limitations when applied individually; however, a synergistic approach combining both PDT and PTT could overcome these shortcomings. Protoporphyrin (PpIX) is an effective and widely used PS for PDT but in its molecular form, its application is hindered by significant biopharmaceutical drawbacks, such as high hydrophobicity.

Green-synthesized silver nanoparticles (AgNPs) exhibit outstanding antibacterial and antioxidant potential for designing and developing nanomedicines and medical devices. Nephelium lappaceum or rambutan contains polyphenol-based phytochemicals, which suggests its suitability for the green synthesis of NPs. However, the lack of a systematic approach directly impacts the robustness and reproducibility of the process. Design of experiments can address these challenges in obtaining NPs with the desired quality profile. In this work, we demonstrated the advantages of a Plackett–Burman model in the semi-automated green synthesis of AgNPs using N. lappaceum peel extract. The extract concentration was the only significant factor affecting the particle size. The optimized NPs exhibited triangular and hexagonal morphologies and a hydrodynamic diameter of 80 nm after 24 h without a stabilizing agent, representing 1.2% prediction error according to the model’s equation. The in vitro antioxidant capacity was confirmed through the ABTS radical scavenging assay. The AgNPs displayed a minimum inhibitory concentration of 23.5 µg mL⁻¹ against Escherichia coli and Staphylococcus aureus. Overall, this work highlights the synergistic role between a DoE-assisted green synthesis, the phytochemicals from N. lappaceum peel extract, and the formed AgNPs, positioning this systematic approach as a sustainable and efficient process for novel antibacterial and antioxidant agents.

Eco-friendly therapeutic deep eutectic solvent-based nanoparticles (ENPs) were functionalized with hyaluronic acid to improve their ability to target CD44 receptors overexpressed on various cancer cells. The ENPs were prepared using microfluidics.

The present work consists in developing new organic crystalline nanomedicines, namely co-nanocrystals (co-NCs), that associate a chemotherapy with an anti-inflammatory active pharmaceutical ingredient (API) in their nanocrystalline forms. These mixed...

There has been a recent paradigm shift among scientists concerning the development of novel anticancer diagnostic and treatment agents. The interest lies in the utilization of nanomedicine which has triggered significant attention in cancer research. At present, nanomedicine has transformed the current landscape of science through the use of numerous nanoformulations not only in cancer diagnosis but also in treatment. Nanoformulations including but not limited to polymeric, lipidic, metallic, crystal, and quantum dots nanomaterials have been demonstrated to play a pivotal role in circumventing major challenges associated with anticancer medications such as targeting cancer cells and reducing side effects. The use of nanomaterials in cancer is largely attributed to their distinct tunable features such as small size, improved drug loading, high sensitivity, high surface area‐to‐volume ratio, and site specificity, all of which are key in the development of next‐generation antitumoural formulations. Additionally, the versatility of these nanomedicine formulations extends to the overall improvement of the bioavailability of antitumoural medicines. Consequently, researchers are investigating the potential use of nanomaterials in oncology to improve tumor diagnosis and treatment. This article focuses on the potential role of nanomedicines in breast cancer diagnosis and treatment using polymeric, lipidic, metallic, organic, quantum dot nanomaterials which are promising for innovant therapies and personalized nanomedicine.

Nanochitin is a nanoscale form of chitin—a polysaccharide found in the exoskeletons of crustaceans, insects, and some fungal cell walls—that is newly garnering significant attention in the pharmaceutical space. Its good properties, such as biocompatibility, biodegradability, and an easily adjustable surface, render it attractive for various medical and pharmaceutical applications.
