“…A better understanding of the interactions between cells and NPs is becoming increasingly important as cellular therapies are very promising for regenerative medicine, especially repair of tissue function after organ damage. 53 Nanomaterials could influence the fate of differentiation of these cells or enable the detection of migration and homing of cells. To track the migration and homing of transplanted cells 13 , techniques like bioluminescence 54 , !…”

“…A bottom-up approach to produce films with inorganic NPs is the production of film forming hybrid organic/inorganic polymeric aqueous dispersions; namely, waterborne nanocomposite latexe's. Among the different techniques that can be used to produce these nanocomposite polymeric dispersions, miniemulsion polymerization has shown the highest success and versatility because hybrid polymer particles with complex morphologies can be tailored [19][20][21][22]. This technique is environmentally friendly and allows a better control of the NPs dispersion throughout the polymer matrix [23][24][25][26].…”

a b s t r a c tThis study addresses the preparation and characterization of hybrid films prepared from Titanium dioxide (TiO 2 ) Pickering stabilized acrylic polymeric dispersion as well as their bacterial inactivation efficiency under sunlight irradiation. Complete bacterial inactivation under low intensity simulated solar light irradiation (55 mW/cm 2 ) was observed within 240 min for the films containing 10 weight based on monomers (wbm) % of TiO 2 , whereas 360 min were needed for the films containing 20 wbm% of TiO 2. The hybrid films showed repetitive Escherichia coli (E. coli) inactivation under light irradiation. TiO 2 released from the films surfaces was measured by inductively coupled plasma mass spectrometry (IPC-MS), obtaining values of ∼0.5 and 1 ppb/cm 2 for the films containing 10 wbm% and 20 wbm% of TiO 2 , respectively, far below the allowed cytotoxicity level for TiO 2 (200 ppb). Transmission electron microscopy (TEM) of the hybrid films showed that TiO 2 nanoparticles (NPs) were located at the polymer particle's surface forming a continuous inorganic network inside the film matrix. Atomic force microscopy (AFM) images showed differences in the TiO 2 dispersion between the air-film and film-substrate interfaces. Films containing 10 wbm% of TiO 2 had higher roughness (Rg) at both interfaces than the one containing 20 wbm% of TiO 2 inducing an increase in the bacterial adhesion as well as the bacterial inactivation kinetics. The highly oxidative OH• -radicals participating in the bacterial inactivation were determined by fluorescence.

“…Miniemulsions are a special class of emulsions that are stabilized by surfactant (including costabilizer against Ostwald ripening) and high-energy homogenization, and usually yield stable and narrowly distributed droplets with a size ranging from 50 to 500 nm [35]. Because polymers can be synthesized in the dispersed phase of a miniemulsion system, at the interface of the droplets, or in the continuous phase, minimulsion droplets can be used as templates for the formation of a micro/nanocapsule shell [35,36], in terms of the so-called miniemulsion polymerization encapsulation.…”
