TL;DR: This work proves covalent nanoparticles-polymer bond formation by liquid NMR after dissolution of the functionalized MOF under mild conditions and estimates the amount of covalently attached polymer by UV–vis spectroscopy.
Abstract: Selective functionalization of the external surface of porous nanoparticles is of great interest for numerous potential applications in the field of nanotechnology. Regarding metal–organic frameworks (MOFs), few methods for such modifications have been reported in the literature. Herein, we focus on the covalent attachment of functional polymers on the external surface of MIL-100(Fe) nanoparticles in order to implement properties such as increased chemical and colloidal stability or dye-labeling for the investigation of the particles by fluorescence based techniques. We prove covalent nanoparticles-polymer bond formation by liquid NMR after dissolution of the functionalized MOF under mild conditions and estimate the amount of covalently attached polymer by UV–vis spectroscopy. The functionalization of the MOF nanoparticles with fluorescently labeled polymers enables the investigation of nanoparticle uptake into tumor cells by fluorescence microscopy. Furthermore, the influence of the polymer shell on the ...

TL;DR: The results showed that cell retention on the modified PLLA was much higher than that on the unmodified one, and the parallel plate flow chamber is an effective device for evaluating the effects of surface modification on the cell affinity of a material.

TL;DR: In this paper, the authors have named the liquid-phase plasma "solution plasma" and developed solution plasma processing (SPP) to synthesize of nanoparticles, surface modification of metals, and sterilization of water.
Abstract: Liquid-phase plasma is not well known, although it has been used sparingly in water treatments and electrical discharge machining. We have named the liquid-phase plasma "solution plasma" and developed solution plasma processing (SPP). This paper reports the applications of SPP to syntheses of nanoparticles, surface modification of metals, and steril- ization of water.

TL;DR: Modulation of nanoparticles reactivity to the biological environment by the choice of materials and surface functionalization may provide new directions in the design of multifunctional nanomedicines with predictable fate.
Abstract: Safe implementation of nanotechnology and nanomedicine requires an in-depth understanding of the life cycle of nanoparticles in the body. Here, we investigate the long-term fate of gold/iron oxide heterostructures after intravenous injection in mice. We show these heterostructures degrade in vivo and that the magnetic and optical properties change during the degradation process. These particles eventually eliminate from the body. The comparison of two different coating shells for heterostructures, amphiphilic polymer or polyethylene glycol, reveals the long lasting impact of initial surface properties on the nanocrystal degradability and on the kinetics of elimination of magnetic iron and gold from liver and spleen. Modulation of nanoparticles reactivity to the biological environment by the choice of materials and surface functionalization may provide new directions in the design of multifunctional nanomedicines with predictable fate.
