Photopolymerization of diacetylene-capped gold nanoparticles
Marina Alloisio,Anna Demartini,Carla Cuniberti,Maurizio Muniz-Miranda,Emilia Giorgetti,Anna Giusti,Giovanna Dellepiane +6 more
TL;DR: Gold nanoparticles coated with the diacetylene henicosa-10,12-diyn-1-yl (DS9) disulfide were successfully prepared by direct synthesis in toluene solutions and showed that in these assemblies the monomer undergoes an intra-particle polymerization and that the dominant polydiacetylene phase present is ruled by the core size.

Photopolymerization in water of diacetylenes chemisorbed onto noble metal nanoparticles: a spectroscopic study
Corinna Raimondo,Marina Alloisio,Anna Demartini,Carla Cuniberti,Giovanna Dellepiane,Sushilkumar A. Jadhav,Giovanni Petrillo,Emilia Giorgetti,Cristina Gellini,Maurizio Muniz-Miranda +9 more
TL;DR: In this article, topochemical polymerization of colloidal suspensions was obtained by UV irradiation and studied by means of spectroscopic techniques (UV-visible absorption, IR and Raman spectroscopies).

Silver-polydiacetylene core–shell nanohybrids: From nano to mesoscale architectures
Marina Alloisio,Stefania Zappia,Anna Demartini,M. Isabel Martinez Espinoza,Massimo Ottonelli,Giovanna Dellepiane,Sergio Thea,Ornella Cavalleri,Ranieri Rolandi +8 more
TL;DR: In this paper, a model of the polyPCDA self-assembled on silver nanoparticles was proposed and the surface coverage density was evaluated, which showed that the resulting nanohybrids are very stable in aqueous suspension and exhibit a bilayered, core-shell architecture.

TL;DR: The proposed functionalization with fluorescent compounds opens the way to the application of metal NCs using double-wavelength detection, with considerable potential especially for in vivo medical applications, as the plasmonic band is centered in the visible light region where biological fluids and tissues are transparent.

Chitosan-Stabilized Noble Metal Nanoparticles: Study of their Shape Evolution and Post-Functionalization Properties
TL;DR: Gold and gold-silver anisotropic nanostructures were synthesized in very high shape-yields through a wet, seed-mediated approach based on the use of nearly spherical silver nanoparticles as seeds and chitosan as stabilizing agent to obtain versatile, chromic platforms suitable for sensing and spectroscopic purposes.
