Apart from improvements in well established methods based on conventional fluorescence microscopy and confocal microscopy (fluorescence in situ hybridisation (FISH), tyramide signal amplification (TSA) in immunocytochemistry, new fluorophores), more recently introduced techniques like fluorescence resonance energy transfer (FRET), fluorescence recovery after photobleaching (FRAP), multiphoton microscopy and fluorescence correlation spectroscopy (FCS) will be discussed.展开更多

The weak native fluorescence imaging for Zephyranthes candida (Lindl.) Herb. Pollen cells can be realized within 1 min. The spatial resolution of 0 6 μm per pixel has been achieved with a 40× objective. The imaging speed, sensitivity and spatial resolution are satisfactory, hence the system has a good application prospect in cell biology and medicine. Some factors that influence imaging speed and quality have been discussed preliminarily.展开更多
