Method for preparation of Ag and Au nanoparticles by extract of lyophilised biomass of green algae Parachlorella kessleri
Description of the technology Silver (Ag) and gold (Au) nanoparticles are currently widely used in a variety of applications (from electronics to biomedicine); however, the procedures for their preparation is often environmentally unfriendly. The use of biological methods for their production is more acceptable from an environmental point of view; on the other hand it often results in poor control over their size or shape. Green microscopic algae are infrequently used for nanoparticle production. The subject of the innovation is a new method for the preparation of Ag and Au nanoparticles using an extract from lyophilised biomass of the alga Parachlorella kessleri. By mixing the extract with silver or gold solutions it is possible to prepare sufficiently stable spherical nanoparticles of Ag or nanoparticles of Au with a narrow size distribution.
