Fabry-Pérot Microscopy for Improved Contrast Enhancement and Quantitative Phase Imaging. [PDF]

J Biophotonics
Fabry‐Pérot Microscopy (FPM) integrates a tunable laser and on‐chip optical cavity to amplify contrast within biological samples, achieving up to 20× enhancement. This label‐free technique enables quantitative phase imaging and discrimination of different cell types based on their optical thickness. ABSTRACT Fabry‐Pérot microscopy (FPM) is a label‐free

Soft Interferometric Nanostrain Sensor Reveals Solid-Liquid Interfacial Tension Oscillation Amplified by Competitive Adsorption. [PDF]

Small
An interferometric nanostrain sensor is developed to investigate unlabeled protein adsorption by directly measuring real‐time interfacial tensions at unprecedented resolution (<0.25 mN m−1). A high‐frequency, low‐amplitude oscillation of the interfacial tension is found to be superimposed over the Langmuir adsorption.
