Descripción de la oferta
We are seeking a highly motivated predoctoral researcher who will work in an interdisciplinary and international environment with leading groups in the field. It is foreseen that the candidate will perform some research stays in our collaborator laboratories. The candidate will apply for other Predoctoral fellowships such as FPU (Spanish Government) or FI (Generalitat de Catalunya), as well as other similar Fellowships from other agencies.
Research Topic
In living systems, tiny chemical signals switch complex processes on and off. CHEMOPTFOR brings that idea to photonics: instead of controlling optical forces only by tweaking laser settings (color, power, polarization), we will use molecules as the remote control for light’s push and pull. You’ll design chromophore‑doped particles whose color or excited‑state lifetime changes reversibly with simple chemical inputs (pH, ions, quenchers). Those molecular switches will let us strengthen or weaken optical forces on demand: first on single particles, then in self‑assembling “optical matter” that forms reconfigurable patterns for photonic crystals, sensing, and smart materials. Along the way you’ll work with state‑of‑the‑art optical traps and microscopes, learn practical soft‑matter and dye chemistry, and turn models into experiments in fluids, not just in ideal vacuum conditions.
Your research aims to demonstrate chemically modulated optical trapping for (bio)chemical sensing in complex media, creating a new class of optochemically responsive materials. This is frontier territory: chemistry has largely sat on the sidelines of optical forces. We plan to change that, positioning physical chemists at the heart of optical manipulation. If you’re excited by hands‑on experimentation, elegant physical ideas, and real‑world impact, you’ll find plenty of first‑author opportunities, international collaborations, and mentoring across chemistry, physics, materials, and bioengineering. Bring your curiosity; we’ll help you build the skills to make adaptive, light‑driven materials that think (and react) like living systems.
