Direct visualization of superselective colloid-surface binding mediated by multivalent interactions
Christine Linne, Daniele Visco, Stefano Angioletti-Uberti +2
Reliably distinguishing between cells based on minute differences in receptor density is crucial for cell-cell or virus-cell recognition, the initiation of signal transduction and…
Combinatorial entropy behaviour leads to range selective binding in ligand-receptor interactions
Meng Liu, Azzurra Apriceno, Miguel Sipin +6
From viruses to nanoparticles, constructs functionalized with multiple ligands display peculiar binding properties that only arise from multivalent effects. Using statistical mecha…
Non-Equilibrium Uptake Kinetics of Molecular Cargo into Hollow Hydrogels Tuned by Electrosteric Interactions
Arturo Moncho-Jorda, Alicia Germain-Bellod, Stefano Angioletti-Uberti +2
In this work, we use a combination of a phenomenological effective cosolute-hydrogel interaction potential and Dynamic Density Functional Theory to investigate the full non-equilib…
Interaction of Proteins with Polyelectrolytes: A Comparison between Theory and Experiment
Xiao Xu, Stefano Angioletti-Uberti, Yan Lu +2
We discuss recent investigations of the interaction of polyelectrolytes with proteins. In particular, we review our recent studies on the interaction of simple proteins such as hum…
Catalysis by metallic nanoparticles in solution: Thermosensitive microgels as nanoreactors
Rafael Roa, Stefano Angioletti-Uberti, Yan Lu +3
Metallic nanoparticles have been used as catalysts for various reactions, and the huge literature on the subject is hard to overlook. In many applications, the nanoparticles must b…
Catalyzed bimolecular reactions in responsive nanoreactors
Rafael Roa, Won Kyu Kim, Matej Kanduc +2
We describe a general theory for surface-catalyzed bimolecular reactions in responsive nanoreactors, catalytically active nanoparticles coated by a stimuli-responsive 'gating' shel…
Exploiting Receptors Competition to Enhance Nanoparticles Binding Selectivity
Stefano Angioletti-Uberti
Nanoparticles functionalized with multiple ligands can be programmed to bind biological targets depending on the receptors they express, providing a general mechanism exploited in…
Reaction rate of a composite core-shell nanoreactor with multiple, spatially distributed embedded nano-catalysts
Marta Galanti, Duccio Fanelli, Stefano Angioletti-Uberti +3
We present a detailed theory for the total reaction rate constant of a composite core-shell nanoreactor, consisting of a central solid core surrounded by a hydrogel layer of variab…
Thermosensitive Cu2O-PNIPAM core-shell nanoreactors with tunable photocatalytic activity
He Jia, Rafael Roa, Stefano Angioletti-Uberti +9
We report a facile and novel method for the fabrication of Cu2O@PNIPAM core-shell nanoreactors using Cu2O nanocubes as the core. The PNIPAM shell not only effectively protects the…
Simple approach for calculating the binding free energy of a multivalent particle
Nicholas B. Tito, Stefano Angioletti-Uberti, Daan Frenkel
We present a simple yet accurate numerical approach to compute the free energy of binding of multivalent objects on a receptor-coated surface. The method correctly accounts for the…
Resonance Reaction in Diffusion-Influenced Bimolecular Reactions
Jakob J. Kolb, Stefano Angioletti-Uberti, Joachim Dzubiella
We investigate the influence of a stochastically fluctuating step-barrier potential on bimolecular reaction rates by exact analytical theory and stochastic simulations. We demonstr…
Theory and Simulation of DNA-Coated Colloids: a Guide for Rational Design
Stefano Angioletti-Uberti, Bortolo M. Mognetti, Daan Frenkel
By exploiting the exquisite selectivity of DNA hybridization, DNA-Coated Colloids (DNACCs) can be made to self-assemble in a wide variety of structures. The beauty of this system s…
Theory of Solvation-Controlled Reactions in Stimuli-Responsive Nanoreactors
Stefano Angioletti-Uberti, Yan Lu, Matthias Ballauff +1
Metallic nanoparticles embedded in stimuli-responsive polymers can be regarded as nanoreactors since their catalytic activity can be changed within wide limits: the physicochemical…
