Metal nanoparticles are established tools for biomedical applications due to their unique optical properties, primarily attributed to localized surface plasmon resonances. They show distinct optical characteristics, such as high extinction cross-sections and resonances at specific wavelengths, which are tunable across the wavelength spectrum by modifying the nanoparticle geometry. These attributes make metal nanoparticles highly valuable for sensing and imaging in biology and medicine.

Microtia, along with trauma, represents one of the main causes of external ear malformation. Different clinical techniques were developed for the reconstruction of the auricle, but they all have some drawbacks. This work is focused on the development of an innovative 3D porous scaffold, printed by Fused Deposition Modelling (FDM) and based on laser-scanned images of the healthy contralateral ear of the patient.

Gemcitabine (GEM), a chemotherapeutic agent, is widely utilized in treating various neoplasm conditions, such as pancreatic, lung, breast, and ovarian cancers. However, its therapeutic effectiveness is often hindered by its hydrophilic nature, short half-life and susceptibility to enzymatic degradation. To address these limitations, in this research, five new prodrugs of GEM were synthesized by conjugating its N-4 amino group with five different acids [4-decenoic acid (4Dec), lipoic acid (Lipo), lauric acid (Laur), 5-benzyl N-(tert-butoxycarbonyl)- L-glutamate (Glu), and decanoic acid (Dec)].

Psoriatic arthritis (PsA), a chronic inflammatory disease, mainly affects the joints, with approximately 30% of psoriasis patients eventually developing PsA. Characterized by both innate and adaptive immune responses, PsA poses significant challenges for effective treatment. Recent advances in drug delivery systems have sparked interest in developing novel formulations to improve therapeutic outcomes.
