- The importance of spheroids in analyzing nanomedicine efficacyPublication . Mó, Inês; Sabino, Ivo; Melo-Diogo, Duarte de; Sousa, Rita Lima; Alves, Cátia; Correia, I.J.The use of nanomedicines for cancer treatment holds a great potential due to their improved efficacy and safety. During the nanomedicine preclinical in vitro evaluation stage, these are mainly tested on cell culture monolayers. However, these 2D models are an unrealistic representation of the in vivo tumors, leading to an inaccurate screening of the candidate formulations. To address this problem, spheroids are emerging as an additional tool to validate the efficacy of new therapeutics due to the ability of these 3D in vitro cancer models to mimic the key features displayed by in vivo solid tumors. In this review, the application of spheroids for the evaluation of nanomedicines' physicochemical properties and therapeutic efficacy is discussed.
- Assessing the Combinatorial Chemo‐Photothermal Therapy Mediated by Sulfobetaine Methacrylate‐Functionalized Nanoparticles in 2D and 3D In Vitro Cancer ModelsPublication . Mó, Inês; Alves, Cátia; Diogo, Duarte de Melo; Sousa, Rita Lima; Correia, I.J.Combinatorial cancer therapies mediated by nanomaterials can potentially overcome the limitations of conventional treatments. These therapies are generally investigated using 2D in vitro cancer models, leading to an inaccurate screening. Recently, 3D in vitro spheroids have emerged in the pre-clinical testing stage of nanomedicines due to their ability to mimic key features of the in vivo solid tumors.
