Science Connect II: Prof. Liz-Marzán

· Glasgow

 

We are delighted to host Prof. Luis M. Liz-Marzán, professor at Ikerbasque and scientific director of CIC biomaGUNE in San Sebastián since 2012, as part of the Science Connect seminar series.

 

“Plasmonic Nanoparticles. Synthesis, Self-Assembly and Applications in Biosensing”

Nanoplasmonics can be defined as the science studying the manipulation of light using materials of size much smaller than the radiation wavelength. This technology finds applications in various fields including sensing and diagnostics. An essential component of nanoplasmonics are the nanostructured materials, typically noble metals, which can very efficiently absorb and scatter light because of their ability to support coherent oscillations of free (conduction) electrons. Although the remarkable optical response of “finely divided” metals is well known since more than 150 years ago, the recent development of sophisticated characterization techniques and modeling methods has dramatically reactivated the field. An extremely important pillar on which the development of nanoplasmonics has been based comprises the impressive advancement in fabrication methods, which provide us with an exquisite control over the composition and morphology of nanostructured metals. Colloid chemistry methods in particular have the advantage of simplicity and large scale production, while offering a number of parameters that can be used as a handle to direct not only nanoparticle morphology but also surface properties and subsequent processing.

This talk will be based on a selection of fabrication methods that allow fine tuning of the morphology of nanoplasmonic building blocks, with the ultimate goal of improving their optical properties and their performance in sensing applications. Several examples will be presented in which nanostructured materials comprising gold nanoparticles were used as substrates for ultrasensitive detection of biorelevant molecules.

 

Some Information about the event:

Professor Liz-Marzán will give this seminar on Tuesday 23rd October, at 4 pm.

Where? At the Carnegie Lecture Theatre, School of Chemistry, University of Glasgow, which is located at University Avenue, G12 8QQ, Glasgow.

This event is free for everyone, no tickets needed. All people interested in attending are warmly invited!

We will also have a networking session after the seminar with snacks and drinks. If you wish to attend this session, please book a ticket using this link, since spaces are limited.

We are looking forward to seeing you there!
