Design of Stimuli‐Responsive Cobalt Tetraphenylporphyrinate‐Chitosan Microspheres for Advanced Biosensors

open access: yesEuropean Journal of Inorganic Chemistry, EarlyView.
We report on new cobalt tetraphenylporphyrinate‐chitosan‐based microspheres developed for biosensing and anticancer therapy applications. We analyzed their second‐harmonic generation (SHG) behavior using a high‐resolution SHG microscope. In addition to the typical porphyrinate fluorescence, the microspheres exhibit a high‐intensity SHG response and ...

Gender Mainstreaming in Urban Food Policies: Governance Processes and Policy Designs From Three Spanish Cities

open access: yesEuropean Policy Analysis, EarlyView.
ABSTRACT This paper explores the integration of gender mainstreaming in urban food policies (UFPs) through three Spanish case studies: Barcelona, Valencia, and Zaragoza. While UFPs are pivotal for addressing sustainability in urban food systems, attention to gender disparities within them remains insufficient.
