• ; redox-responsive nanocarrier; viologen cavitand; Introduction Photodynamic therapy (PDT) is a minimally invasive, clinically approved approach widely utilized for cancer treatment, as well as various non-malignant conditions. It relies on three key components, namely, light, molecular oxygen, and a

• amplify PDT efficacy [34][35][36]. We developed a redox-responsive nanocarrier for targeted THPP delivery. Monodisperse nanoparticles (THPP@p(MVCA-BAC), see below Scheme 1) were synthesized through self-assembly of viologen functionalized resorcinarene cavitand with acrylate groups on the low rim (MVCA
