In this episode, we're exploring the fascinating intersection of nanotechnology and biology with Dr. Boghossian, who has been delving into the remarkable properties and potential of single-walled carbon nanotubes (SWCNTs) for cell nanobiotechnology.

Our discussion revolves around Dr. Boghossian's groundbreaking work examining the uptake of SWCNTs in Gram-negative cyanobacteria. Her research uncovers a passive length-dependent and selective internalization of SWCNTs decorated with positively charged biomolecules, a previously unexplored aspect of SWCNT functionalization for transport across prokaryotic cell walls.

Notably, her team showed that lysozyme-coated SWCNTs spontaneously penetrate the cell walls of both unicellular and multicellular strains. Using a custom-built spinning-disc confocal microscope, they were able to image the d ...
