Biodegradable hollow silica nanospheres containing gold nanoparticle arrays

Voliani back cover for Royal Chemestry

In a new paper accepted on “Chemical Comunication” journal Valerio Voliani and collaborators presented a highly reproducible, functional and biodegradable nanosystem composed of hollow silica nanoparticles in which 3 nm gold nanoparticles are embedded in their central cavity in a narrow array, capable of simulating the optical behaviour of a single larger gold nanoparticle. Noticeably, these nanosystems stand as promising tools to overcome the issue of accumulation of inorganic nanoparticles in organisms. Preliminary in vivo photoacoustic and X-ray experiments are ongoing. Also, the possibilities to develop gold arrays with peculiar geometries (and thus peculiar optical behaviour, such as rods) and nanosystems devoid of metal nanoparticles are under investigation.

Nanotecnologie sotto la torre: caffè scientifici al CNI IIT@NEST a Pisa

IIT si racconta

Il 13 e il 27 maggio, presso il Caffè Letterario Volta Pagina di Pisa si terranno due incontri per scoprire le nanotecnologie, le tecnologie che lavorano sulla scala del miliardesimo di metro, con i ricercatori del Center for Nanotechnology Innovation dell’Istituto Italiano di Tecnologia di Pisa (CNI - IIT@NEST). La formula sarà quella degli ormai consolidati Caffè Scientifici organizzati da IIT a Genova. Un ambiente informale in cui conoscere i ricercatori dell’Istituto Italiano di Tecnologia e comprendere l’importanza della ricerca scientifica per il nostro futuro. L’iniziativa si rivolge ad un pubblico non specialistico e i ricercatori comunicheranno in un linguaggio accessibile a tutti la loro passione per la scienza.

Richard Shilton is winnner of Premio NEST 2015

Richard Shilton winner of NEST prize 2015

Prize is awarded to all young researchers under 35 years old, who carry out the activities at NEST, who have distinguished themselves for the publication in the nanotechnologies and nanoscience during the previous year with sponsorship from the company RIVOIRA.

This year stood out our young researcher, Richard Shilton, with the publication of the article "Nanoliter-Droplet Acoustic Streaming Ultra High Frequency Surface Acoustic Waves", published in Advanced Materials.

A new technique to study the movement of molecules inside cells

Pnas figure Researchers at the Center for Nanotechnology Innovation (CNI) of the Istituto Italiano di Tecnologia, in collaboration with the NEST Laboratory of Scuola Normale Superiore of Pisa and the University of California at Irvine have recently published a work on ‘Nature Communications’, one of the most prestigious scientific journals in the world, which could in principle revolutionize cell biology.
The study describes a new microscopy technique capable of investigating the movement of molecules, such as proteins, nucleic acids, and even ions, within the cell at unprecedented spatial and temporal resolution. The new technique has allowed identifying hitherto elusive intracellular water-filled nano-cavities used by molecules to efficiently move across the cellular environment and reach their destination.

Il Center for Nanotechnology Innovation all'IF2014

IF2014 La Scuola Normale Superiore e il Center for Nanotechnology Innovation dell'IIT parteciperanno all’Internet Festival 2014 con un collegamento dalla camera bianca del centro NEST in streaming verso l’auditorium del CNR. Tema della partecipazione (ore 17:30 del 10 Ottobre 2014) “Le materie prime del futuro: visita ai laboratori del NEST”, con il seguente abstract: Dai nanofili di semiconduttori ai dispositivi ibridi superconduttori-metallo normale, dal grafene alle nanoparticelle: il nanomondo si svela attraverso la microscopia elettronica a scansione (SEM). In diretta streaming dalla clean room del NEST per parlare di nanoscienza e nanostrutture e per “vedere e manipolare il nanomondo ed i nanomateriali” con l’aiuto degli elettroni . 

In collegamento dall'Auditorium del CNR : Camilla Coletti
