How can we reliably track nanoparticles inside biological tissues? Join the METRINO Academy session 4 on Thursday 26 March 2026 at 3 pm CET, and find out how correlative multimodal imaging workflows can improve the reliability of nanoparticle biodistribution studies by combining complementary analytical techniques within a structured, metrology driven pipeline (interactive Q&A included).

Understanding where nanoparticles go in biological systems is critical for assessing their efficacy and safety in nanomedicine. However, nanoparticle biodistribution studies often rely on isolated imaging methods, leading to fragmented datasets and limited comparability between laboratories.
The METRINO Academy session #4 introduces a systematic pipeline for correlative imaging, designed to integrate multiple analytical techniques applied to the same region of interest within tissue samples. Using NaYF4 nanoparticles embedded in 3D tissue models and phantom tissue calibrators, the presentation will demonstrate how complementary methods including two photon excitation fluorescence microscopy (TPEF), SEM-EDX, ToF-SIMS and LA-ICP-MS can be combined within a structured analytical workflow.
By linking non destructive and high sensitivity techniques in a defined sequence, the approach establishes correlations between primary and indirect nanoparticle detection methods. The session will also highlight how these protocols feed into the METRINO interlaboratory comparison organised within the EURAMET framework, supporting the development of harmonised measurement approaches for nanomedicine research.

Reliable nanoparticle localisation requires combining multiple imaging techniques within a coherent analytical strategy. In this session, we will cover:
Open to both experts and non experts working in nanomedicine, imaging technologies, nanoparticle characterisation, metrology, analytical chemistry, quality control, regulatory science, or method development, whether from academia, industry, metrology institutes, or standards bodies.
1:15 hour (hands on talk + live Q&A). Cameras welcome. Microphones muted by default.
