| Abstract | Properties of nanoparticles (NPs) are responsible for their interaction with various biomolecules such as proteins in biological environments. Amount and composition of the proteins associated with NPs, i.e. protein corona, are strongly dependent on physicochemical characteristics of the particles, as well as incubation parameters including temperature and protein concentration. More importantly, the protein corona can define the biological fate of the NPs. Here, we demonstrate that variations in the concentration of plasma protein led to significant changes in the composition of the hard corona adsorbed on the surface of different NPs including hydrophilic amorphous silica (SiO$_{2}$), hydrophilic crystalline zeolite (EMT), and hydrophobic sulfonated-modified polystyrene. Alteration in the corona composition of the NPs is a result of the plasma concentration, i.e. it affects the release of inflammatory cytokines in a plasma concentration-dependent manner. The amorphous silica nanoparticles with hydrophilic surfaces induced the release of the inflammatory cytokines interleukin-8 (IL-8) and tumor necrosis factor (TNFα) in 10 % plasma concentration, but not at higher concentrations. A reverse trend was observed for the hydrophobic, sulfonated-modified polystyrene NPs. Remarkably the hydrophilic highly porous EMT NPs exhibited no cellular toxicity regardless to the plasma concentration. The results obtained in this study can be used to define optimal pathways for nanoparticles administration in vivo. These findings can assist researchers to better understand how NPs with different surface properties may interact with various proteins in vivo, and elucidate safety considerations for their biomedical applications. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
