NIR Light-Mediated Photocuring of Adhesive Hydrogels for Noninvasive Tissue Repair via Upconversion Optogenesis

Dominique Pioletti, Christophe Moser, Peyman Karami, Yanheng Guo, Vijay Kumar Rana, Antoine Vincent Boniface

The surgical treatments of injured soft tissues lead to further injury due to the use of sutures or the surgical routes, which need to be large enough to insert biomaterials for repair. In contrast, the use of low viscosity photopolymerizable hydrogels tha ...

A constrained method for lensless coherent imaging of thin samples

Michaël Unser, Christophe Moser, Manon Rostykus

Lensless inline holography can produce high-resolution images over a large field of view (FoV). In a previous work [Appl. Opt.60, B38 (2021)], we showed that (i) the actual FoV can be extrapolated outside of the camera FoV and (ii) the effective resolution ...
