This seminar is hosted by Dr. Valle Palomo.


In the past two decades, there has been a notable increase in interest regarding the application of plasmonic nanoparticles as light-triggered heat sources, leading to the establishment of the field known as thermoplasmonics.1 This development has had a significant impact on various research domains, including catalysis, stimulus-responsive materials, and biomedicine. In this talk we will briefly review our recent research activities related to the use of plasmonic nanoparticles and light in various contexts. First, we will discuss the feasibility of utilizing gold nanorods with reversible clustering properties to construct a light-driven colloidal self-oscillator, a new type of nanosystem capable of exhibiting periodic responses to non-periodic stimuli.2,3 Second, we will explore the use of metal-polymer heterojunction to enhance the photo-regeneration of biomolecules, cofactors, using visible and NIR light sources.4 Third, we will delve into our recent research activities concerning plasmon-mediated photo-modulation of neuronal activity in vitro.
