Hybrid Multiphoton Lithography Scaffolds for Nanoscale Mechanobiological Assessment in Microscale Bone Models. [PDF]

Small
This work presents a 3D hybrid tissue scaffold inspired by bone, incorporating collagen, fabricated using multiphoton lithography. The mechanical properties of collagen are tunable, and biodegradation allows for time‐dependent changes in geometry. The results demonstrate enhanced osteogenic differentiation of stem cells in our hybrid scaffolds.

Monitoring the transdermal delivery of fluorescent nanoparticles using multiphoton fluorescence microscopy [PDF]

SPIE Proceedings, 2004
An interesting area of applying multiphoton fluorescence microscopy is in investigating the delivery of fluorescent nanoparticles (quantum dots) across biological barriers such as the skin. Fluorescence nanoparticles are nanometer in size and understanding the delivery mechanisms of these materials across the skin can be important in understanding the ...

Copper–Collagen Interactions Regulate the Mechanical and Invasive Properties of Tumor Spheroids

Advanced Healthcare Materials, EarlyView.
Ionic copper is investigated as a modulator of tumor spheroid growth and invasiveness in a 3D microfluidic glioblastoma model. Copper exposure alters metabolic activity, cytoskeletal organization, protrusion dynamics, and EMT‐related phenotypes in a dose‐ and timing‐dependent manner, revealing how copper bioavailability shapes tumor aggressiveness ...

Methodology for reconstructing early zebrafish development from in vivo multiphoton microscopy

, 2012
Investigating cell dynamics during early zebrafish embryogenesis requires specific image acquisition and analysis strategies. Multiharmonic microscopy, i.e., second- and third-harmonic generations, allows imaging cell divisions and cell membranes in ...
