Project description
A new era for biological imaging
Biological imaging faces challenges in visualising subcellular structures without altering or damaging them. Traditional methods often rely on labels that can perturb the biological environment. The ERC-funded Beyond the visible project will revolutionise this field with a super-resolution, label-free Raman microscope. This technology uses an ambient-air field detector and ultrafast femtosecond electromagnetic forces at petahertz frequencies, allowing for non-invasive imaging. By coherently driving molecular vibrations and employing temporal confinement, it achieves high signal-to-noise ratios and sensitivity. This project promises to deliver chemically sensitive images without labels, setting new standards for spatial resolution and detection, thereby enabling groundbreaking advancements in biomedical research and beyond.
Objective
The next generation of biological imaging will be a movement towards super-resolution, label-free approaches to visualize subcellular structures in a nonperturbative, non-invasive manner. In this proposal, a super-resolution, label-free, Raman microscope based on a novel, ambient-air, field-detector is envisioned to fulfil the requirements of these exciting prospects, essential for biomedical advancements. By employing bright, ultra-broadband, femtosecond electromagnetic forces at petahertz frequencies, Raman molecular vibrations are driven coherently and efficiently. Temporal confinement of the excitation pulses to a few femtoseconds allows for temporal filtering of the molecular response and therefore, a high signal-to-noise ratio, and high detection sensitivity is achieved. The same laser provides optical pulses with ultrashort duration to directly access and detects the field oscillations of the emitted Raman molecular response. This novel detection metrology allows for simultaneous and broadband detection of the entire molecular fingerprint and beyond with high dynamic range and sensitivity down to quantum shot noise. Most importantly, due to the near-field imaging in this scheme super-resolution, chemically sensitive images can be constructed without the need for labeling molecules or using structured light. The advanced near-infrared femtosecond source in combination with the novel field detection technology will enable acquiring the complete fingerprint of complex biological molecules non-invasively with a spatial resolution and sensitivity exceeding that of any previously demonstrated method, for the first time. The next generation of laser-driven biological microscopy requires a dramatic leap in sensitivity, dynamic range, spatial resolution, and non-invasiveness; this proposal represents a coherent, achievable approach to fulfilling this need opening up new horizons for fundamental studies in science to see beyond the visible.
