Characterisation of engineered nanomaterials (NMs) is of outmost importance for the assessment of the potential risks arising from their extensive use. NMs display indeed a large variety of physico-chemical properties that drastically affect their interaction with biological systems. Among them, hydrophobicity is an important property that is nevertheless only slightly covered by the current ph...

Abstract Micro-and nanorobots have the potential to perform non-invasive drug delivery, sensing, and surgery in living organisms, with aid of diverse medical imaging techniques. To such actions, microrobots require high spatiotemporal resolution tracking real-time closed-loop feedback. that end, photoacoustic has appeared as a promising technique for deep tissue higher molecular specificity con...
