- ItemA guide to super-resolution fluorescence microscopy(New York, NY : Rockefeller Univ. Press, 2010) Schermelleh, L.; Heintzmann, R.; Leonhardt, H.For centuries, cell biology has been based on light microscopy and at the same time been limited by its optical resolution. However, several new technologies have been developed recently that bypass this limit. These new super-resolution technologies are either based on tailored illumination, nonlinear fluorophore responses, or the precise localization of single molecules. Overall, these new approaches have created unprecedented new possibilities to investigate the structure and function of cells. © 2010 Schermelleh et al.
- ItemsimpleISM—A straight forward guide to upgrade from confocal to ISM(San Francisco, California, US : PLOS, 2022) Goswami, Monalisa; Lachmann, René; Kretschmer, Robert; Heintzmann, RainerResolution in a confocal laser scanning microscopes (CLSM) can be improved if the pinhole is closed. But closing the pinhole will deteriorate the signal to noise ratio (SNR). A simple technique to improve the SNR while keeping the resolution same by upgrading the system to an image scanning microscope. In this paper, we explain in detail, based on an Olympus Fluoview 300 system, how a scanning microscope can be upgraded into an image scanning microscope (ISM) using a simple camera-based detector and an Arduino Due providing a galvo driving and camera synchronization signals. We could confirm a resolution improvement as well as superconcentration and made the interesting observation of a reduced influence of laser fluctuations.
