Carbon nanotube dispersion for in-vitro applications
Carbon nanotubes (CNTs) have gained popularity due to their many characteristics which make them the promising material for biomedical applications. A major challenge when working with CNTs is the difficulty to distribute them evenly throughout liquids. This research is a comparative analysis of the...

This research is a comparative analysis of the dispersion of multi wall CNTs (MWCNTs) in different liquid media (distilled water, ultrapure water of type I [Milli-Q], ethanol, dimethyl sulfoxide [DMSO] and cell culture medium [RPMI-1640]) by using two different sonication techniques (probe-type sonication and ultrasonic bath sonication) as well as determining the effect of sterilization in the presence and absence of fluid before dispersion. The results indicate that the best method to achieve a CNTs dispersion is to use a probe-type sonicator as well as to sterilize the CNTs samples in the presence of fluid.Los nanotubos de carbono (CNTs) han atraído un enorme interés debido a sus muchas características que los convierten en un material prometedor para aplicaciones biomedicas. Un desafío importante cuando se trabaja con CNTs es la dificultad de dispersarlos homogéneamente en un fluido. Esta investigación es un análisis comparativo de la dispersión de nanotubos de carbono de pared múltiple (MWCNTs) en diferentes fluidos (agua destilada, agua ultrapura de tipo I [Milli-Q], etanol, dimetilsulfóxido [DMSO] y medio de cultivo celular [RPMI-1640]). Utilizando dos diferentes técnicas de sonicación (sonicación con lanza ultrasónica y sonicación ultrasónica de baño), así como la determinación del efecto de la esterilización en presencia y ausencia de fluido antes de la dispersión. Los resultados indican que el mejor método de dispersión de los CNTs es usando un sonicador tipo lanza y esterilizarlos en presencia de fluido.application/pdfspaUniversidad Nacional de Colombia (Sede Medellín).

Carbon nanotubes (CNTs) have gained popularity due to their many characteristics which make them the promising material for biomedical applications. A major challenge when working with CNTs is the difficulty to distribute them evenly throughout liquids. This research is a comparative analysis of the dispersion of multi wall CNTs (MWCNTs) in different liquid media (distilled water, ultrapure water of type I [Milli-Q], ethanol, dimethyl sulfoxide [DMSO] and cell culture medium [RPMI-1640]) by using two different sonication techniques (probe-type sonication and ultrasonic bath sonication) as well as determining the effect of sterilization in the presence and absence of fluid before dispersion.
