“Dr Corneile Minnaar, a pollination biologist from Stellenbosch University in South Africa has come up with a new idea of using quantum dots and 3D printed fluorescence box to track the fate of individual pollen grains. This novel, low-cost method could enable pollination biologists to track the whole pollination process from the first visit by a pollinator to its endpoint – either successfully transferred to another flower’s stigma or lost along the way…”
