Super‐Resolution Stimulated Raman Scattering Microscopy with Graphical User Interface–Supported A‐PoD

Abstract

AbstractRaman microscopy is a vibrational imaging technology that can detect molecular chemical bond vibrational signals. Since this signal is originated from almost every vibrational mode of molecules with different vibrational energy levels, it provides spatiotemporal distribution of various molecules in living organisms without the need for any labeling. The limitations of low signal strength in Raman microscopy have been effectively addressed by incorporating a stimulated emission process, leading to the development of stimulated Raman scattering (SRS) microscopy. Furthermore, the issue of low spatial resolution has been resolved through the application of computational techniques, specifically image deconvolution. In this article, we present a comprehensive guide to super‐resolution SRS microscopy using an Adam‐based pointillism deconvolution (A‐PoD) algorithm, complemented by a user‐friendly graphical user interface (GUI). We delve into the crucial parameters and conditions necessary for achieving super‐resolved images through SRS imaging. Additionally, we provide a step‐by‐step walkthrough of the preprocessing steps and the use of GUI‐supported A‐PoD. This complete package offers a user‐friendly platform for super‐resolution SRS microscopy, enhancing the versatility and applicability of this advanced microscopy technique to reveal nanoscopic multimolecular nature. © 2024 The Authors.
