Magnetic Janus particles have been studied extensively for medical and biological applications owing to their controllable mobility in fluid media. In this work, we report a novel microfluidic device designed for the synthesis of magnetically anisotropic Janus particles made of poly(ethylene glycol) diacrylate and embedded with magnetic iron oxide nanoparticles. Our method consists of a droplet generation step followed by magnetic separation using an external magnetic field and ultraviolet polymerization. The synthesized particles exhibit a monodisperse size distribution with a standard deviation of less than 3.5%, which is among the best size distributions obtained in the literature for magnetic Janus particles. The anisotropic magnetic property of the particles enable them to rotate about their own axes in the presence of an external magnetic field, introducing another degree of freedom to their motion. This microfluidic technique is simple, one-step, and versatile, offering control over the size distribution to synthesize magnetically anisotropic Janus particles.

Multifunctional polymers are interesting substances for the formulation of drug molecules that cannot be administered in their pure form due to their pharmacokinetic profiles or side effects. Polymer-drug formulations can enhance pharmacological properties or create tissue specificity by encapsulating the drug into nanocontainers, or stabilizing nanoparticles for drug transport. We present the synthesis of multifunctional poly(2-ethyl-2-oxazoline--2-glyco-2-oxazoline)s containing two reactive end groups, and an additional hydrophobic anchor at one end of the molecule.

This study introduces a novel approach for non-small cell lung cancer (NSCLC) treatment by developing BiSe-Polysorbate nanoparticles as a multifunctional platform for photothermal therapy and targeted drug delivery. The BiSe-Polysorbates nanoparticles are engineered as innovative photosensitive drug carriers, enhancing biocompatibility through the combination of BiSe and Polysorbates. Characterization techniques such as Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and ultraviolet-visible (UV-Vis) spectroscopy confirm the successful synthesis of the nanoparticles.

Activatable multifunctional nanoparticles present considerable advantages in cancer treatment by integrating both diagnostic and therapeutic functionalities into a single platform. These nanoparticles can be precisely engineered to selectively target cancer cells, thereby reducing the risk of damage to healthy tissues. Once localized at the target site, they can be activated by external stimuli such as light, pH changes, or specific enzymes, enabling precise control over the release of therapeutic agents or the initiation of therapeutic effects.

To design a multifunctional nanozyme hydrogel with antibacterial, photo-responsive nitric oxide-releasing, and antioxidative properties for promoting the healing of infected wounds. We first developed ultra-small silver nanoparticles (NPs)-decorated sodium nitroprusside-doped Prussian blue (SNPB) NPs, referred to as SNPB@Ag NPs, which served as a multifunctional nanozyme. Subsequently, this nanozyme, together with geniposide (GE), was incorporated into a thermo-sensitive hydrogel, formulated from Poloxamer 407 and carboxymethyl chitosan, creating a novel antibacterial wound dressing designated as GE/SNPB@Ag hydrogel.
