Nanomedicine systems offers multiple benefits in treating chronic respiratory and tumoral diseases by site-specific, and target-oriented delivery of precise medicines, employing materials in the nanoscale range. In this context, South Korea has become one of the most active countries. In particular, Yonsei university is one of the most research-intensive institute, with a thriving community of innovative and world-leading researchers. Within this scenario, an heterogenous team in the medical research department of Wonju, composed by nanotechnologists, biologists and engineers, is working on micro-sized polymeric PLGA-based discoidal particles as carriers for the transport and delivery of lung-targeted drugs, in order to improve the therapeutic efficiency and safety of such theranostic systems.
