Dr. Valeria Castelletto is a prominent researcher in the Department of Chemistry at the University of Reading, within the School of Chemistry, Food and Pharmacy. She is a key member of a leading research group focused on peptide-based biomaterials and soft matter physics, collaborating extensively with Professor Ian W. Hamley. Her work bridges chemistry, materials science, and biophysics, with a strong emphasis on the design and characterization of functional nanostructures.
Her research interests center on the self-assembly of peptides and lipopeptides, exploring how molecular structure dictates the formation of nanotubes, micelles, hydrogels, and other complex nanostructures. She investigates the biophysical properties of these materials using advanced techniques like small-angle scattering (SAXS/SANS), electron microscopy, and spectroscopy. A major focus is on functional biomaterials for applications in nanomedicine, including antimicrobial agents, drug delivery systems, wound healing, and cancer vaccines. Her recent work highlights the role of chirality, sequence, and environmental triggers (like pH) in controlling self-assembly and bioactivity.
The trends in her recent publications (2024-2025) demonstrate a sophisticated approach to designing multifunctional peptide conjugates. Her research integrates immunology (e.g., TLR agonists), regenerative medicine (e.g., wound healing peptides), and fundamental physical chemistry (e.g., phase separation, micellization) to create next-generation biomaterials. The consistent publication in high-impact journals like ACS Nano, Biomacromolecules, and Soft Matter underscores the significance and quality of her contributions to the field of supramolecular chemistry and nanobiotechnology.
While specific scientific awards are not listed in the provided text, her prolific publication record in top-tier journals is a strong indicator of peer recognition. Her research is undoubtedly supported by competitive grants, enabling her to lead a productive research program. She is likely involved in the supervision and mentoring of PhD students and postdoctoral researchers, contributing to the training of the next generation of scientists.
Her work is conducted within a well-equipped laboratory environment focused on peptide synthesis, biophysical characterization, and in vitro/in vivo bioactivity testing. The team employs a multidisciplinary approach, combining chemical synthesis with advanced physical analysis to understand and engineer the properties of peptide-based materials for real-world applications.
