Heterogeneous collapse in thermoresponsive copolymer microgels varying molar composition
Jacopo Vialetto, Francesco Brasili, Letizia Tavagnacco +5
Understanding the internal architecture of copolymer microgels is crucial for establishing how nanoscale polymer organization controls their stimuli-responsive behavior. Here we fo…
Using fast-reactive crosslinkers to modulate the internal structure of thermoresponsive microgels
Ballin Elisa, Brasili Francesco, Sztucki Michael +3
The internal architecture of poly(N-isopropylacrylamide) (PNIPAM) microgels, which switches from fuzzy-sphere to star-like when the standard N,N'-methylenebis(acrylamide) (BIS) cro…
Phase behavior of thermoresponsive colloids drives re-entrant plasmon coupling
Angela Capocefalo, Francesco Brasili, Javier Pérez +8
Plasmonic nanoparticles (NPs) integrated within thermoresponsive polymeric microgels provide a versatile platform for the realization of stimuli-responsive optical materials, where…
Star-like microgels vs star polymers: similarities and differences
Tommaso Papetti, Elisa Ballin, Francesco Brasili +1
Star-like microgels have recently emerged as a promising class of thermoresponsive soft colloids, that have an internal architecture similar to that of star polymers. Here, we perf…
Thermoresponsive copolymer microgels synthesized via single-step precipitation polymerization: random or block structure?
Letizia Tavagnacco, Elena Buratti, Jacopo Vialetto +9
The inner structure of polymeric particles critically influences their phase behavior and functionality, governing their mechanical properties and their physical and chemical inter…
Star-like thermoresponsive microgels: a new class of soft nanocolloids
Elisa Ballin, Francesco Brasili, Tommaso Papetti +5
We provide experimental and numerical evidence of a new class of soft nanocolloids: star-like microgels with thermoresponsive character. This is achieved by using the standard prec…
Linking structure and optical properties of plasmonic nanoparticles on tunable spherical surfaces
Francesco Brasili, Angela Capocefalo, Giovanni Del Monte +8
The complexation of plasmonic nanoparticles (NPs) and thermoresponsive microgels is widely exploited for applications, but a microscopic description of the mechanisms governing the…
Toward a unified description of the electrostatic assembly of microgels and nanoparticles
Francesco Brasili, Giovanni Del Monte, Angela Capocefalo +6
The combination of soft responsive particles, such as microgels, with nanoparticles (NPs) yields highly versatile complexes of great potential for applications, from ad-hoc plasmon…
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…
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…
DNA-functionalized gold nanoparticle assemblies for Surface Enhanced Raman Scattering
D. Caprara, F. Ripanti, A. Capocefalo +5
The programmable assembly of DNA strands is a promising tool for building tailored bottom-up nanostructures. Here, we present a plasmonic nanosystem obtained by the base-pairing me…
