Nanoscale local modification of PMMA refractive index by tip-enhanced femtosecond pulsed laser irradiation

Autor: Tranca, Denis E., Stanciu, Stefan G., Hristu, Radu, Ionescu, Adrian M., Stanciu, George A.

Investigation techniques based on tip-enhanced optical effects, capable to yield spatial resolutions down to nanometers level, have enabled a wide palette of important discoveries over the past twenty years. Recently, their underlying optical setups

On the Automated Detection of Corneal Edema with Second Harmonic Generation Microscopy and Deep Learning

Autor: Anton, Stefan R., Martínez-Ojeda, Rosa M., Hristu, Radu, Stanciu, George A., Toma, Antonela, Banica, Cosmin K., Fernández, Enrique J., Huttunen, Mikko, Bueno, Juan M., Stanciu, Stefan G.

When the cornea becomes hydrated above its physiologic level it begins to significantly scatter light, loosing transparency and thus impairing eyesight. This condition, known as corneal edema, can be associated with different causes, such as corneal

rSHG: Re-scan Second Harmonic Generation Microscopy

Autor: Stanciu, Stefan G., Hristu, Radu, Stanciu, George A., Tranca, Denis E., Eftimie, Lucian, Dumitru, Adrian, Costache, Mariana, Stenmark, Harald A., Manders, Harm, Cherian, Amit, Tark-Dame, Mariliis, Manders, Erik M. M.

Second Harmonic Generation Microscopy (SHG) is generally acknowledged as a powerful tool for the label-free 3D visualization of tissues and advanced materials, with one of its most popular applications being collagen imaging. Although the great need,
