Salient features of medical nanoparticles in biological fluids from an analytical ultracentrifuge

Abstract

In perspective of future translation, medical, biodegradable nanoparticles (NPs) have been investigated by an analytical ultracentrifuge in fluids of various complexity, including human serum, in a temperature range of 6 to 40 °C, and timescales relevant for a nanomedical targeting and clearance application. These studies provided salient insights on integrity and degradation aspects of the NPs, imposed by the varying solution environmental conditions. This was enabled by selective monitoring of the targeting dye moiety, cell-specifically directing the NPs to the desired location of interest, i.e. considering a future translative in vivo application. Our study provides experimental insights that are believed being of key importance to gauge feasibility of such translative applications in terms of (i) compatibility with patient sera, (ii) timescales of targeting success, and (iii) timescales of desired erosion enabling clearance from the target. All such aspects are provided a priori any in vivo implementation.
