The development of pH-responsive nanoparticles for controlled and selective drug release represents a notable advance in adaptive nanomedicine. This study explores the design of a pH-responsive polymer, poly(1,4-phenyleneacetone dimethylene ketal) (PPADK). Additionally, the incorporation of light-responsive ortho-nitrobenzyl groups (o-NB-PPADK) enhanced the degradation upon exposure to light. Based on the polymer, nanoparticles were prepared using the solvent displacement method. The fluorescence dye Lumogen® Red was incorporated as a model substance. The nanoparticles were characterized by dynamic light scattering to determine their hydrodynamic diameter and size distribution, and the surface charge was analyzed. Atomic force microscopy was used to visualize the surface morphology. The nanoparticles remained stable under physiological pH conditions while exhibiting accelerated degradation and substance release in acidic environment, a property potentially exploitable for tumor targeting. Further enhanced degradation and correspondingly increased release was achieved by incorporating light-responsive elements in the polymer structure.\r\nThe cytotoxicity of these newly designed nanoparticles was evaluated in cell culture using a breast cancer cell line. These results support the potential of o-NB-PPADK nanoparticles as a possible candidate for selective and effective cancer therapy, combining stimuli-responsive degradation mechanisms for improved therapeutic outcomes."}],"status":"public","_id":"64884","user_id":"94","department":[{"_id":"163"}],"article_type":"original","article_number":"126127","keyword":["Nanoparticles","Drug delivery","Controlled release","Stimuli-responsiveTumor targeting"],"language":[{"iso":"eng"}]},{"_id":"30927","department":[{"_id":"311"}],"user_id":"94","keyword":["catechol chemistry","poly(caffeic acid)","polyelectrolyte complex coatings","thermoresponsive coatings","controlled release","bortezomib","multiple myeloma"],"article_number":"6081","language":[{"iso":"eng"}],"publication":"International Journal of Molecular Science","type":"journal_article","status":"public","publisher":"MDPI","date_updated":"2022-04-21T09:00:31Z","volume":20,"author":[{"first_name":"Berthold","full_name":"Reis, Berthold","last_name":"Reis"},{"first_name":"David","full_name":"Vehlow, David","last_name":"Vehlow"},{"first_name":"Tarik","full_name":"Rust, Tarik","last_name":"Rust"},{"first_name":"Dirk","id":"287","full_name":"Kuckling, Dirk","last_name":"Kuckling"},{"full_name":"Müller, Martin","last_name":"Müller","first_name":"Martin"}],"date_created":"2022-04-21T09:00:09Z","title":"Thermoresponsive Catechol Based-Polyelectrolyte Complex Coatings for Controlled Release of Bortezomib","doi":"10.3390/ijms20236081","publication_status":"published","issue":"23","year":"2019","intvolume":"        20","citation":{"apa":"Reis, B., Vehlow, D., Rust, T., Kuckling, D., &#38; Müller, M.
