Abstract Multicolor microscopy and super-resolution optical are two widely used techniques that greatly enhance the ability to distinguish resolve structures in cellular imaging. These methods have individually transformed imaging by allowing detailed visualization of subcellular structures, as well organelle interactions. However, integrating multicolor into a single method remains challenging due issues like spectral overlap, crosstalk, photobleaching, phototoxicity, technical complexity. challenges arise from conflicting requirements using different fluorophores for labeling with specific properties We propose novel called phasor-based fluorescence spatiotemporal modulation (Phasor-FSTM). This uses time-resolved detection acquire data encoded photons, employs phasor analysis simultaneously separate multiple components, applies create images. Phasor-FSTM enables identification structural components greater spatial accuracy on an enhanced laser scanning confocal microscope single-wavelength laser. To demonstrate capabilities Phasor-FSTM, we performed two-color four-color at resolution ~λ/5 observed interactions organelles live cells during continuous duration over 20 min. Our stands out its simplicity adaptability, seamlessly fitting existing microscopes without requiring lines excitation, which also provides new avenue other technologies based principles build multi-color systems requirement lower budget.

Super-resolution microscopy techniques, and specifically single-molecule localization (SMLM), are approaching nanometer resolution inside cells thus have great potential to complement structural biology techniques such as electron for cell biology. In this review, we introduce the different flavors of super-resolution microscopy, with a special emphasis on SMLM MINFLUX (minimal photon flux). We summarize recent technical developments that pushed these localization-based scales review experimental conditions key obtaining data highest quality. Furthermore, give an overview analysis methods highlight studies used gain insights into biologically relevant molecular machines. Ultimately, our perspective what is needed push even further apply them investigating dynamic rearrangements in living cells.

Lipid nanoparticles (LNPs) have recently emerged as a powerful and versatile clinically approved platform for nucleic acid delivery, specifically mRNA vaccines. A major bottleneck in the field is release of mRNA-LNPs from endosomal pathways into cytosol cells where they can execute their encoded functions. The data regarding mechanism these escape processes are limited contradicting. Despite extensive research, there no consensus compartment escape, cause inefficient currently lacking robust method to detect escape. Here, we review known mechanisms available methods study this process. We critically discuss limitations challenges possibilities overcome challenges. propose that development robust, quantitative high-throughput techniques timely essential. better understanding process will enable RNA-LNP designs with improved efficiency unlock new therapeutic modalities.

Abstract A fundamental challenge in fluorescence microscopy is the photon shot noise arising from inevitable stochasticity of detection. Noise increases measurement uncertainty and limits imaging resolution, speed sensitivity. To achieve high-sensitivity beyond shot-noise limit, we present DeepCAD-RT, a self-supervised deep learning method for real-time suppression. Based on our previous framework DeepCAD, reduced number network parameters by 94%, memory consumption 27-fold processing time factor 20, allowing two-photon microscope. high signal-to-noise ratio can be acquired with tenfold fewer photons than standard approaches. We demonstrate utility DeepCAD-RT series photon-limited experiments, including vivo calcium mice, zebrafish larva fruit flies, recording three-dimensional (3D) migration neutrophils after acute brain injury 3D dynamics cortical ATP release. will facilitate morphological functional interrogation biological minimal budget.

Here, we present polarization-splitting scheme combines Stochastic Optical Reconstruction Microscopy (STORM) with molecule 2D wobbling measurements, without requiring strong deformation imaged point spread function.
