Leishmania brasiliensis, promastigotes

Leishmania brasiliensis Promastigotes and Natural Rubber Membranes... 

The characteristic spectrum of the NR membrane shows no characteristic bands when evaluated in the UV-vis area. Absorption bands are observed around 560 nm, attributed to the plasmon resonance of the gold nanoparticles. The incorporation of the blue methylene molecules is observed through the absorption bands at 595 and 667 nm, assigned to 7t-jt electronic transitions. These membranes were then evaluated in culture medium of promastigotes of Leishmania brasiliensis, when irradiated with blue light, and the results are shown in Figure 26.4.
