The research activity is focused on the development and application of methodologies based on nanosecond pulsed lasers to investigate in general photophysical processes and in particular the dynamics of protein structural changes. This broad field encompasses both structural events involved in protein folding and structural changes associated with protein function.
SA has actively contributed to develop an experimental method to introduce fast changes in proton concentration in solution. The integrated use of photoactivatable (caged) compounds and nanosecond laser flash photolysis has allowed to obtain large pH jumps on the nanosecond time scale, stable for several seconds, that allowed for investigating micro- and nanosecond events in proteins.
- fluorescent probes to visualize intracellular processes with further developments of the technique foreseen in single molecule and in vivo.
- the use of a photochemical trigger to study the functional dynamics and fundamental properties as allosteric mechanisms, ligand migration, structural relaxation and reactivity of hemoproteins.
- photochromic proteins and bacterical photoreceptors for super resolution microscopy
- photosensitizers for antimicrobial and tumor photodynamic therapy
SA’s research activity had allowed her to acquire an in depth knowledge of time resolved techniques - photothermal methods as time resolved photoacoustics, and optical methods as laser flash photolysis with transient absorption and fluorescence emission detection – fluorescence correlation spectroscopy and numerical data analysis. These methods allow to investigate light induced reactions, which include also photochemical rearrangements of autofluorescent protein chromophores and, more generally, other photochemical reaction intermediates with different chromophoric properties.
