Particle surfaces to study macrophage adherence, migration, and clearance

Septiadi, Dedy ; Lee, Aaron ; Spuch‐Calvar, Miguel ; Moore, Thomas Lee ; Spiaggia, Giovanni ; Abdussalam, Wildan ; Rodriguez‐Lorenzo, Laura ; Taladriz‐Blanco, Patricia ; Rothen‐Rutishauser, Barbara ; Petri‐Fink, Alke

In: Advanced Functional Materials, 2020, p. 2002630

Nanoparticle adsorption to substrates pose a unique challenge to understand uptake mechanisms as it involves the organization of complex cytoskeletal components by cells to perform endocytosis/phagocytosis. In particular, it is not well‐understood from a cell mechanics perspective how the adhesion of particles on substrate will influence the ease of material clearance. By using a particle...

Metal nanoparticle–microbe interactions: synthesis and antimicrobial effects

Khan, Mujeebur R. ; Fromm, Katharina M. ; Rizvi, Tanveer F. ; Giese, Bernd ; Ahamad, Faheem ; Turner, Raymond J. ; Füeg, Michael ; Marsili, Enrico

In: Particle & Particle Systems Characterization, 2020, vol. 37, no. 5, p. 1900419

Metal nanoparticles (NPs), chalcogenides, and carbon quantum dots can be easily synthesized from whole microorganisms (fungi and bacteria) and cell‐free sterile filtered spent medium. The particle size distribution and the biosynthesis time can be somewhat controlled through the biomass/metal solution ratio. The biosynthetic mechanism can be explained through the ion‐reduction theory and...
