Designing Ligand-functionalized Nanoparticles: Insights from Theory and Simulations
ProfessorStefano Angioletti-Uberti
Time: Thursday, Dec. 8, 2:00-3:00 pm
Place: BUCT Library Center Conference Room


Designing new functional materials as well as optimizing the performance of existing ones necessarily requires a solid understanding of the physical principles governing their behavior. Without this knowledge, their development would necessarily follow an empirical “trial and error” route, with very little success chances (and high costs), especially for complex materials where the number of parameters determining their behaviour is large. In this regard, theory and computational simulations can serve as an important tool to guide experiments, as well as to screen a priori the effect of specific parameters choices in a controlled environment.

Following this line, I will present in this talk our recent results in the theoretical description of ligand-functionalized nanoparticles (with emphasis on DNA-coated colloids). These materials are studied for various applications, including the self-assembly of photonic structures, DNA-biosensors and vectors for drug-delivery, and I will show how our models can and have been used not only to understand their behavior and guide their optimization, but also to suggest completely new designs resulting in new, unprecedented properties.


ProfessorStefano Angioletti-Ubertireceived his Master degree in2007 in Materials Science at the University of Milano-Bicocca (Italy), and then he moved to the UK at Imperial College London, where he obtained his PhD in Materials Science in 2010.He did his first postdoc at the Chemistry Department of the University of Cambridge, where he began to study DNA-coated colloids and their theoretical description in the group of Prof. DaanFrenkel. In 2013, he moved to Germany at the Humboldt University of Berlin, where he kept working on the properties of various types of functionalized nanoparticles, nanogels and their applications. 


In 2015, he joined the Beijing Advanced Innovation Centre for Soft Matter Science and Engineering as a PI and Professor of Soft Matter. While he still holds a part-time position in Beijing, from October 2016 hejoined the Department of Materials at Imperial College London, UK, where hefocus on theory and simulation of nanomaterials for biomedical applications.
