چکیده
In vivo incorporation of a series organometallic photoluminescent complexes in Phaeodactylum tricornutum diatom shells (frustules) is investigated as biotechnological route to luminescent biosilica nanostructures. [Ir(ppy)2bpy]+[PF6]−, [(2,2′-bipyridine)bis(2-phenylpyridinato)iridium(III) hexafluorophosphate], [Ru(bpy)3]2+ 2[PF6]−, [tris(2,2′-bipyridine)ruthenium(II) AlQ3 (tris-(8-hydroxyquinoline)aluminum), and ZnQ2 (bis-8-hydroxyquinoline-zinc) are used model explore the potentiality generality process. The added culture, resulting silica nanostructures isolated by an acid-oxidative treatment that removes organic cell matter without altering both frustule morphology photoluminescence incorporated emitters. Results show that, except for ZnQ2, protocol successfully leads into biosilica. spontaneous self-adhering ability bare doped cells on conductive indium tin oxide (ITO)-coated glass slides observed, which can be exploited generate dielectric biofilms living microorganisms with shells. general, this envisaged profitable new functional nanostructured materials photonics, sensing, or biomedicine via chemical modification frustules

Genome properties of the diatom Phaeodactylum tricornutum.
Diatoms are a ubiquitous class of microalgae of extreme importance for global primary productivity and for the biogeochemical cycling of minerals such as silica. However, very little is known about diatom cell biology or about their genome structure. For diatom researchers to take advantage of genomics and post-genomics technologies, it is necessary to establish a model diatom species. Phaeodac...
متن کاملRegulation of the Calvin cycle in the diatom Phaeodactylum tricornutum
IV Regulation of the Calvin cycle in the diatom Phaeodactylum tricornutum Phaeodactylum tricornutum is an important model organism for diatoms, one of the prevalent phytoplankton on earth. Diatoms are unicellular, eukaryotic and photoautotrophic microalgae, which contribute greatly to the global carbon cycle efficiently transforming CO2 into carbon compounds via the Calvin cycle pathway. There ...
متن کاملBlue light is essential for high light acclimation and photoprotection in the diatom Phaeodactylum tricornutum
The objective of the present study was to test the hypothesis that the acclimation to different light intensities in the diatom Phaeodactylum tricornutum is controlled by light quality perception mechanisms. Therefore, semi-continuous cultures of P. tricornutum were illuminated with equal amounts of photosynthetically absorbed radiation of blue (BL), white (WL), and red light (RL) and in combin...
متن کاملGene silencing in the marine diatom Phaeodactylum tricornutum
Diatoms are a major but poorly understood phytoplankton group. The recent completion of two whole genome sequences has revealed that they contain unique combinations of genes, likely recruited during their history as secondary endosymbionts, as well as by horizontal gene transfer from bacteria. A major limitation for the study of diatom biology and gene function is the lack of tools to generate...
