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.

Aptamers: challenging targets

AptmarsThe discovery and realization of new molecular systems able to recognize with high precision a biological target have been recently described on the international journal Molecular Therapy Nucleic Acids . Authors are a research team composed by scientists of NEST, Scuola Normale Superiore and Istituto Nanoscienze-CNR, and of the Center for Nanotechnology Innovation, Istituto Italiano di Tecnologia.

The published results demonstrate that a special class of nucleic acid molecules, aptamers, is promising candidate as molecular systems for diagnostic and therapeutic applications, particularly when their targets are cell-surface receptors. In particular, researchers at CNI generated an enhanced DNA aptamer that selectively binds to the transferrin receptor, a cell-surface protein that is over-expressed in many tumors and on the endothelium of the blood brain barrier. They started from two interconvertible conformers of a known DNA aptamer, identified the active one, and engineered it to obtain an enhanced, more stable version by punctual mutations employing a rational optimization strategy. The improved aptamer represents a valid and innovative tool for targeted drug delivery both in vitro and in vivo.

The ABC of trilayer graphene

Graphene TimeThe “wonder material” graphene is an active focus of research at the Center for Nanotechnology Innovation, IIT@NEST. Recently, trilayer graphene has attracted wide attention owing to its stacking and electric-field-dependent electronic properties. However, a direct and well-resolved experimental visualization of its band structure was never reported before today.

Our work, entitled “Revealing the electronic band structure of trilayer graphene on SiC: An angle-resolved photoemission study,” fills this gap by presenting high-resolution angle-resolved photoemission spectroscopy (ARPES) data which reveal for the first time the electronic band structure of trilayer graphene obtained on silicon carbide via hydrogen intercalation. The electronic bands of both stable forms of trilayer graphene – i.e., Bernal (ABA) and rhombohedral (ABC), differing for the vertical stacking of the individual carbon layers – were observed with a remarkable agreement with theoretical calculations from tight-binding models.

Notably, our study shows that on SiC substrates the occurrence of ABC-stacked trilayer is significantly higher than in natural bulk graphite. This still-to-be-explained finding might open an unexpected route towards the fabrication of a new class of gap-tunable devices because the ABC-stacked trilayer graphene is the most appealing form of trilayer for electronic applications, thanks to its tunable band-gap, but it is also the most uncommon in natural graphite.

The study was performed in collaboration with scientists from the Max-Planck Institute of Stuttgart, the Istituto Nanoscienze-CNR and Scuola Normale Superiore, the MAX-lab of Lund, the University of South Carolina, the Laboratoire des Matériaux et du Génie Physique of Grenoble and the University of Texas at Austin.
