The photos we see here were taken from a Plescher prepared slide. Plescher fluorescence prepared slides are characterized by a distinctive, three-dimensional, deeply structured honeycomb structure. This is made possible by special, complex, gentle pre-treatment of the hand coupes made of living material that reproduce the sensitive cell contents surprisingly well. The conventional ultra-thin section technology with embedding in paraffin, does not provide the same detailed results. Plescher specimens impress with their specially developed Plescher staining with clarity and gloss, differentiated on a deep black background at 460 - 490 nm excitation wavelength. They are therefore generally ideal for photo stacking.
Wormwood or Artemisia is a plant from the composite family Asteraceae. It is a perennial that occurs naturally in the temperate regions of Europe, Asia and North Africa. The genus Artemisia is derived from the Greek goddess Artemis. The plant is known as one of the tastiest kitchen herbs. The plant grows to 60-120 cm and blooms with light yellow flowers from July to September. A medicinal effect has traditionally been attributed to the buds of wormwood. The bitter extract from these buds is an important component of the vermouth and (classic) absinthe drinks. The flavorings that play a role in this are absinthine and the terpene fragrance that smells like menthol.
