You can find all my A Level Biology videos fully indexed at https://www.freesciencelessons.co.uk/a-level-revision-videos/a-level-biology/

In this video, we look at laser scanning confocal microscopy. First we look at how laser scanning confocal microscopy works. We then look at the advantages of this over conventional light microscopy.
