Expanding Chemical Space of Nucleic Acid Nanoparticles for Tunable Antiviral‐Like Immunomodulatory Responses and Potent Adjuvant Activity

Advanced Functional Materials, EarlyView.
We introduce a nucleic acid nanoparticle (NANP) platform designed to be rrecognized by the human innate immune system in a regulated manner. By changing chemical composition while maintaining constant architectural parameters, we identify key determinants of immunorecognition enabling the rational design of NANPs with tunable immune activation profiles

“Ser bueno es ser feroz”

Semina - Revista dos Pós-Graduandos em História da UPF, 2022
O presente trabalho tem como objetivo discorrer sobre a problemática da violência a partir da oposição entre a violência aberta e a violência estrutural. Parte de uma contextualização crítica a respeito da violência para, posteriormente, encontrar convergências dessas críticas na práxis e nos discursos de Ravachol e Émile Henry, dois conhecidos ...

Multifunctional Microstructured Surfaces by Microcontact Printing of Reactive Microgels

Advanced Functional Materials, EarlyView.
Reactive poly(N‐vinylcaprolactam‐co‐glycidyl methacrylate) microgels are used as functional inks to create surface‐grafted arrays on glass via microcontact printing. The patterns (10–50 µm widths and spacings) enable stable binding and post‐functionalization with dyes and peptides.
