Laser‐Assisted Synthesis of Non‐Equilibrium Nanoalloys

Abstract

Vincenzo Amendola is Professor of Physical Chemistry at Padova University, where he established and directs the Laser‐Assisted Synthesis and Plasmonics (LASP) lab. He obtained a PhD in Materials Science and Engineering in 2008 and the Italian qualification as Full Professor in 2017, after research experience at Massachusetts Institute of Technology and Cambridge University. He is part of the Program Committee of the ANGEL conference series and he is a current member of the ChemPhysChem Editorial Advisory Board.

Recent Developments in Plasmonic Alloy Nanoparticles: Synthesis, Modelling, Properties and Applications

“…Alloying is a strategy to re‐introduce the range of properties of the periodic table into nanostructures with an appreciable plasmonic response (Figure 1 ). [ 12 , 13 ] It is well known that alloying two or more metals leads to new materials with properties that are not simply the average of their monometallic counterparts. In effect, this approach can open the way to multifunctional plasmonic objects of great appeal for several applications and can offer the opportunity of moulding the electronic structure of the metal to improve and maximize the efficacy for a specific plasmonic effect.…”

Laser-generated nanoalloys as theranostic and biodegradable platforms for cancer nanomedicine

“…[1][2][3][4] In this scenario, nanoalloys of biocompatible elements emerged as extremely promising for addressing several of the challenges in the clinical use of inorganic nanomaterials, thus enabling the realization of innovative cancer nanomedicines. 5 The key point with nanoalloys is the choice of the optimal composition regardless of the limits posed by element immiscibility or chemical instability towards oxidation, i.e. bypassing thermodynamic and synthetic challenges.…”

Structural evolution under physical and chemical stimuli of metastable Au–Fe nanoalloys obtained by laser ablation in liquid

“…4 Besides, the portfolio of functional nanostructures is sensibly widened by the inclusion of metastable phases, enabling a list of applications in several key technological elds such as quantum technologies, sustainability, energy conversion and healthcare. [1][2][3][4][6][7][8][9] Metastable phases are oen associated with a complex "ultrastructure" due to incomplete element segregation and chemical coordination, leading to glassy regions mixed with ordered crystalline arrangements of atoms. [10][11][12][13] This "slippery" atomic conformation is difficult to observe even with advanced electron microscopy techniques.…”

“…The comprehension of the time evolution of metastable nanoalloys is the key for enabling new applications and functions where the transformation of the nanomaterial during the process can be a high-value-added feature, which leads to a future generation of dynamic nanotechnologies. 6 At the same time, the investigation of alloy formation during LAL promises to shed light on the main parameters required for the successful control of metastable phases.…”
