  • Antioxidant activity of spirulina biomass at the action of some pegilated nanoparticles 
    RUDI, L.; CEPOI, L.; CHIRIAC, T.; ROTARI, I.; PLÂNGĂU, E.; VALUTA, A.; CARAUȘ, V.; RUDIC, V. (Universitatea de Stat din Moldova, 2019)
    Altering the antioxidant activity of spirulina biomass, in the direction of increase or reduction, is the result of toxic action of xenobiotics on spirulina culture. High concentrations of xenobiotics reduce the antioxidant ...
  • Biochemical changes in cyanobacteria during the synthesis of silver nanoparticles 
    CEPOI, L.; RUDI, L.; CHIRIAC, T.; VALUTA, A.; ZINICOVSCAIA, I.; DUCA, Gh.; KIRKESALI, E.; FRONTASYEVA, M.; CULICOV, O.; PAVLOV, S.; BOBRIKOV, I. (NRC Research Press, 2015)
    The methods of synthesis of silver (Ag) nanoparticles by the cyanobacteria Spirulina platensis and Nostoc linckia were studied. A complex of biochemical, spectral, and analytical methods was used to characterize biomass ...
  • Influence of gold and silver nanoparticles on the synthesis of phycobiliproteins in red microalga Porphyridium cruentum 
    RUDI, L.; CHIRIAC, T.; CEPOI, L.; VALUTA, A.; DJUR, S.; MISCU, V.; CODREANU, S.; TASCA, V.; ROTARI, M. (Institute of Microbiology and Biotechnology, Republic of Moldova, 2022)
    The biological properties of nanoparticles are determined by their size, shape, and surface characteristics. The study of the effect of nanoparticles on microalgae as biotechnological objects is one of the topical areas ...
  • Microalgae as possible silver nanofactories 
    CEPOI, L.; RUDI, L.; CHIRIAC, T.; VALUTA, A.; ZINICOVSCAIA, I.; MITINA, T.; DUCA, Gh.; KIRKESALI, E.; FRONTASYEVA, M. V.; PAVLOV, S. S. (Tehnica UTM, 2013)
    Several strains of microalgae Sprirulina platensis, Nostoc linckia and Porphyridium cruentum were studied to assess their ability of silver nanoparticles formation. In the experiments the synthesis of nanoparticles in ...
  • Procedures for obtaining cyanobacterial and microalgal biomass – source of multifunctional remedies 
    ROTARI, I. D.; TASCA, I.; CARP, E.; ZINICOVSCAIA, I.; IUSHIN, N.; RUDI, L.; CEPOI, L.; CHIRIAC, T.; DJUR, S.; MISCU, V.; DUMBRAVEANU, V.; VALUTA, A.; RUDIC, V. (Academia Forţelor Terestre "Nicolae Bălcescu" din Sibiu, 2020)
    The procedures refer to biotechnology and bionanotechnology in particular to processes for biomass production and cultivation of cyanobacterium Spirulina platensis and microalga Dunaliella salina - sources of multifunctional ...
  • Silver Nanoparticles as Stimulators in Biotechnology of Porphyridium Cruentum 
    CEPOI, L.; RUDI, L.; CHIRIAC, T.; VALUTA, A.; ZINICOVSCAIA, I.; MISCU, V.; RUDIC, V. (Universitatea Tehnică a Moldovei, 2021)
    Silver nanoparticles (AgNPs) are one of the most actively used nanomaterials. Therefore, their release into the environment becomes inevitable. Consequently, studies regarding the harmful effects of AgNPs towards organisms ...
  • Spirulina biomass containing silver nanoparticles – raw and safe material for the development of multipurpose remedies
