The present invention discloses a drug delivery system for targeted therapy comprising a functionalized lipid-based nanoplatform, where at least one ligand is coupled to the surface of the nanoplatform and encapsulates at least one pharmaceutically active ingredient. A process for obtaining the drug delivery system of the present invention is also disclosed as well as a composition comprising the system of the invention. The invention relates to the field of medicine and biotechnology. The present solution aims at developing targeting co-encapsulating nanostructured lipid carriers for the treatment of different types of cancer, including glioblastoma, as well as other diseases and disorders, envisioning the establishment of an in vitro/in vivo correlation.

The invention provides injectable, tough hydrogels that can be crosslinked in situ on demand using minimally-invasive methods, such as visible light exposure is an unmet medical challenge. Among the emerging biopolymers for tissue sealing, gelatin methacryloyl (GelMA), a naturally-derived biopolymer obtained from denatured collagen, has secured a promising role as a result of its excellent bioadhesion, biodegradation, and biocompatibility. To overcome one of the main shortcomings of GelMA, i.e., brittleness, we hybridized it using methacrylate-modified alginate (AlgMA) to impart ion-induced reversible crosslinking that can dissipate energy under strain. The hybrid GelMA-AlgMA hydrogels provide a photocrosslinkable, injectable, and adhesive platform with an excellent toughness that can be engineered using divalent cations, such as calcium. This class of novel hybrid biopolymers with more than 600% improved toughness may set the stage for durable, mechanically-resilient, and cost-effective tissue sealants in minimally invasive procedure, especially for stretchable tissues.
