Near-infrared lensless holographic microscopy on a visible sensor enables label-free high-throughput imaging in strong scattering
Emilia Wdowiak, Piotr Arcab, Mikolaj Rogalski +6
Lensless digital holographic microscopy (LDHM) relies on interference between an unscattered reference wave and a weakly scattered object wave - an assumption that rapidly fails in…

The mixture of glycerin with tartrazine: a solution to reversibly increase tissue transparency for in vitro quantitative phase imaging
Mikolaj Krysa, Anna Chwastowicz, Malgorzata Lenarcik +3
Thick tissue sections strongly scatter and absorb light, which limits transmission-based label-free examination via quantitative phase imaging (QPI) modalities. Here we introduce a…

Low-dose Chemically Specific Bioimaging via Deep-UV Lensless Holographic Microscopy on a Standard Camera
Piotr Arcab, Mikolaj Rogalski, Karolina Niedziela +11
Deep-ultraviolet (DUV) microscopy can provide label-free biochemical contrast by exploiting the intrinsic absorption of nucleic acids, proteins and lipids, offering chemically spec…
