Invited talk

Cancer remains a leading cause of global mortality, with surgical resection serving as the primary curative-intent treatment for early-stage solid tumours. During these interventions, surgeons routinely rely on manual palpation to delineate tumour margins, based on distinct mechanical contrast between rigid malignant lesions and more compliant surrounding stroma. Despite its ubiquity, manual...

Raman spectroscopy is a powerful optical spectroscopy technique that provides a molecular-level fingerprint through inelastic light scattering. However, Raman signals are often weak and obscured by the presence of a strong fluorescent background. Raman scattering arises from an interaction with a virtual state, which is very short-lived. In contrast, fluorescence occurs through excited-state...

250. High-Sensitivity Deep Learning-Enhanced Raman Spectral Classification for Prostate Cancer Detection

Prostate cancer (PCa) is the most diagnosed cancer among males and the second leading cause of cancer death in males in New Zealand. Current diagnosis still relies on biopsy-based tissue sampling and histopathological assessment. During prostate cancer surgery, no tools can assess prostate tissue in real time, thus leading to a high positive surgical margin rate. Raman spectroscopy (RS),...

Optical microscopy is a powerful tool for observing fine structural details and dynamics in biological samples. However, absorption and scattering limit its reach to shallow regions, motivating the use of endoscopic approaches for minimally invasive access to deeper environments. Among these, multimode fibres (MMFs) offer a high information capacity imaging platform within a hair-thin...

772. Escape from and entry of nanoparticles into optical traps

Optical tweezers have been used to trap micro- and nanoparticles varying in size from about 10nm up to many tens of microns. At the small end of this range, particles can be difficult to see, and it is possible for multiple particles to "invisibly" enter the trap. Generally, the higher the power of the trapping beam, the more likely it is that extra particles enter, which can change or corrupt...
