Transmission Structured Illumination Microscopy using Tilt-mirror Assembly
Krishnendu Samanta, Azeem Ahmad, Jean-Claude Tinguely +2
We present experimental demonstration of tilt-mirror assisted transmission structured illumination microscopy (tSIM) that offers a large field of view super resolution imaging. An…
Multi-modal on-chip nanoscopy and quantitative phase image reveals the morphology of liver sinusoidal enodthelial cells
David A. Coucheron, Ankit Butola, Karolina Szafranska +6
Visualization of three-dimensional morphological changes in the subcellular structures of a biological specimen is one of the greatest challenges in life science. Despite conspicuo…
A transparent waveguide chip for versatile TIRF-based microscopy and nanoscopy
Anish Priyadarshi, Firehun Tsige Dullo, Deanna L. Wolfson +6
Total internal reflection fluorescence microscopy (TIRF) has enabled low-background, live-cell friendly imaging of cell surfaces and other thin samples thanks to the shallow penetr…
High spatially sensitive quantitative phase imaging assisted with deep neural network for classification of human spermatozoa under stressed condition
Ankit Butola, Daria Popova, Dilip K Prasad +8
Sperm cell motility and morphology observed under the bright field microscopy are the only criteria for selecting particular sperm cell during Intracytoplasmic Sperm Injection (ICS…
Photonic-chip assisted correlative light and electron microscopy
Jean-Claude Tinguely, Anna Maria Steyer, Cristina Ionica Øie +6
Correlative light-electron microscopy (CLEM) unifies the versatility of light microscopy (LM) with the high resolution of electron microscopy (EM), allowing one to zoom into the co…
A Super-Condenser for Labelfree Nanoscopy
Florian Ströhl, Ida S. Opstad, Jean-Claude Tinguely +5
Labelfree nanoscopy encompasses optical imaging with resolution in the 100 nm range using visible wavelengths. Here, we present a labelfree nanoscopy method that combines Fourier p…
Structured illumination microscopy using a photonic chip
Øystein I. Helle, Firehun T. Dullo, Marcel Lahrberg +2
Structured illumination microscopy (SIM) enables live cell, super-resolution imaging at high speeds. SIM uses sophisticated optical systems to generate pre-determined excitation li…
Sub-nanometer height sensitivity by phase shifting interference microscopy under ambient environmental fluctuations
Azeem Ahmad, Vishesh Dubey, Ankit Butola +3
Phase shifting interferometric (PSI) techniques are among the most sensitive phase measurement methods. Owing to its high sensitivity, any minute phase change caused due to environ…
Influence of surface roughness on the optical properties of plasmonic nanoparticles
Andreas Truegler, Jean-Claude Tinguely, Joachim R. Krenn +2
For plasmonic nanoparticles, we investigate the influence of surface roughness inherent to top-down fabrication on the optical properties, and find that it has a surprisingly small…
Gold Nanoparticles for Plasmonic Biosensing: The Role of Metal Crystallinity and Nanoscale Roughness
Jean-Claude Tinguely, Idrissa Sow, Claude Leiner +5
Noble metal nanoparticles show specific optical properties due to the excitation of localized surface plasmons that make them attractive candidates for highly sensitive bionanosens…
