A spatio-temporal mapping of the uptake of silica (SiO(2)) nanoparticles of different sizes by lung epithelial cells has been obtained. Based on high control of nanoparticle dispersion in cell media and cell exposure, one obtains reproducible and quantitative time-resolved data using a combination of flow cytometry, fluorescence and electron microscopies.… (More)
Nanoparticles (NPs) are increasingly used as biodegradable vehicles to selectively deliver therapeutic agents such as drugs or antigens to cells. The most widely used vehicle for this purpose is based on copolymers of lactic acid and glycolic acid (PLGA) and has been extensively used in experiments aimed at delivering antibiotics against Mycobacterium… (More)
Regulation of biological processes is often based on physical interactions between cells and their microenvironment. To unravel how and where interactions occur, micromanipulation methods can be used that offer high-precision control over the duration, position and magnitude of interactions. However, lacking an in vivo system, micromanipulation has… (More)
