Our laboratory investigates the biomedical potential of metal nanoparticles – including silver, copper, gold, and platinum – as active components in next-generation therapeutic and implant technologies. A central focus is understanding how the physicochemical properties of nanoparticles at the nanoscale level influence their interactions with biological systems, enabling the development of compositions with targeted antibacterial, antitumor, and regenerative effects. By combining advanced synthesis methods with rigorous biological evaluation, we aim to establish clear structure-property-function relationships that guide the rational design of nanoparticle-based medical solutions. One major research direction explores the use of nanocomposites – where metal nanoparticles are integrated into biocompatible organic or inorganic matrices – for selective cancer therapy. Our work demonstrates that such compositions can achieve potent cytotoxic effects against tumor cells while minimizing damage to healthy tissue, offering a promising alternative to conventional chemotherapy with its well-known systemic side effects. This line of research contributes to the broader field of nanomedicine and personalized oncotherapy, areas of growing strategic importance within European healthcare. A second key direction focuses on functional surface modification of orthopedic and osteosynthesis implants using nanoparticle-enriched coatings. By engineering implant surfaces at the nanoscale, we work to simultaneously enhance osseointegration, promote bone tissue regeneration, and reduce the risk of post-operative bacterial infections – one of the most serious complications in orthopedic surgery. These efforts sit at the intersection of materials science and translational medicine, with direct implications for patient outcomes and the long-term sustainability of healthcare systems.
