In particular, we describe results obtained with the fundamental, second and third harmonic of a ps Nd:YAG laser and the influence of laser wavelength and pulse energy on gold particle production and subsequent photofragmentation. In this framework, the role of the dendrimer and, in particular, its interactions with gold clusters and cations are accounted.<\/jats:p>","DOI":"10.3390\/molecules14093731","type":"journal-article","created":{"date-parts":[[2009,9,22]],"date-time":"2009-09-22T12:10:08Z","timestamp":1253621408000},"page":"3731-3753","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":18,"title":["Dendrimer-Capped Nanoparticles Prepared by Picosecond Laser Ablation in Liquid Environment"],"prefix":"10.3390","volume":"14","author":[{"given":"Emilia","family":"Giorgetti","sequence":"first","affiliation":[{"name":"INSTM and Istituto dei Sistemi Complessi, Consiglio Nazionale delle Ricerche, Via Madonna del Piano 10, 50019 Sesto Fiorentino, Firenze, Italy"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anna","family":"Giusti","sequence":"additional","affiliation":[{"name":"Department of Physics \"E.
