Molecular origin of the two-step mechanism of gellan aggregation
Letizia Tavagnacco, Ester Chiessi, Leonardo Severini +10
Among hydrocolloids, gellan is one of the most used anionic polysaccharides, because of its capability of forming mechanically stable gels at relatively low concentrations. Despite…
The role of polymer structure on water confinement in poly(N-isopropylacrylamide) dispersions
E. Buratti, L. Tavagnacco, M. Zanatta +8
Poly(N-isopropylacrylamide) (PNIPAM) is a synthetic polymer that is widely studied for its thermoresponsive character. However, recent works also reported evidence of a low tempera…
Thermoresponsivity of poly(N-isopropylacrylamide) microgels in water-trehalose solution and its relation to protein behavior
Benedetta Petra Rosi, Letizia Tavagnacco, Lucia Comez +8
Hypotheses: Additives are commonly used to tune macromolecular conformational transitions. Among additives, trehalose is an excellent bioprotectant and among responsive polymers, P…
Molecular insights on Poly(N-isoproylacrylamide) coil-to-globule transition induced by pressure
Letizia Tavagnacco, Ester Chiessi, Emanuela Zaccarelli
Poly-N-isopropylacrylamide (PNIPAM) phase diagram is explored in a wide range of temperature and pressure using extensive all-atom molecular dynamics simulations. By exploiting a s…
Atomic scale investigation of the volume phase transition in concentrated PNIPAM microgels
M. Zanatta, L. Tavagnacco, E. Buratti +5
Combining elastic incoherent neutron scattering and differential scanning calorimetry, we investigate the occurrence of the volume phase transition (VPT) in very concentrated PNIPA…
Assembling patchy plasmonic nanoparticles with aggregation-dependent antibacterial activity
Francesco Brasili, Angela Capocefalo, Damiano Palmieri +5
We realise an antibacterial nanomaterial based on the self-limited assembly of patchy plasmonic colloids, obtained by adsorption of lysozyme to gold nanoparticles. The possibility…
Protein-like dynamical transition of hydrated polymer chains
L. Tavagnacco, M. Zanatta, E. Buratti +8
Combining elastic incoherent neutron scattering experiments at different resolutions with molecular dynamics simulations, we report the observation of a protein-like dynamical tran…
Molecular Description of the Coil-to-Globule Transition of Poly(N-isopropylacrylamide) in Water/Ethanol Mixture at Low Alcohol Concentration
Letizia Tavagnacco, Emanuela Zaccarelli, Ester Chiessi
Poly(N-isopropylacrylamide), PNIPAM, is a widely studied polymer, which serves as a key constituent of nanostructured soft materials with responsive properties. Upon increasing tem…
Water-polymer coupling induces a dynamical transition in microgels
Letizia Tavagnacco, Ester Chiessi, Marco Zanatta +2
The long debated protein dynamical transition was recently found also in non-biological macromolecules, such as poly-N-isopropylacrylamide (PNIPAM) microgels. Here, by using atomis…
Evidence of a low-temperature dynamical transition in concentrated microgels
Marco Zanatta, Letizia Tavagnacco, Elena Buratti +5
A low-temperature dynamical transition has been reported in several proteins. We provide the first observation of a `protein-like' dynamical transition in nonbiological aqueous env…
