Self-focusing in multi-photon excitation laser scanning microscopy
Reference Number: 1779 Background In order to view macromolecules within living cells using a light microscope, improvement in resolution is required. Methods for achieving super-resolution have been proposed, however, super-resolving microscopes have had little impact. The reasons are not only high cost and instrumental complexity but each method...
