RESUMEN
OBJECTIVE: The objective of our study was to explore the possible graphene impact on microorganism growth as well as on laboratory animal overall condition. Materials and technique: The experiments applied samples of graphene three concentrations and two 15 × 15 mm quartz glasses one of which carrying deposited graphene lattice. We have also used 5% blood agar, thioglycollate broth, bacterial suspensions of standard turbidity containing pure clinical isolate of microorganisms. Three white male 6-month-old laboratory rats were used to estimate the graphene impact on the overall animal condition. RESULTS: Graphene did not contain any microorganisms, does not destroy erythrocytes placed within the artificial nutritional medium, graphene lattice did not add any properties to the quartz glasses which could allow the Proteus spread all over its surface. It was also established that graphene did not show any native antibacterial impact. No significant reaction was noticed in animals after graphene administration to laboratory rats neither at the injection spot nor at the overall level. CONCLUSION: Our data confirm the applicability of graphene both in scientific and practical biomedical purposes.
