Controlling protein–particle adsorption by surface tailoring colloidal alumina particles with sulfonate groups

Carboxylation and Decarboxylation of Aluminum Oxide Nanoparticles Using Bifunctional Carboxylic Acids and Octylamine

“…The NMR spectrum from the filtrate (Figure 8) shows the presence of the amide N-H at 3.28 ppm. If there was only amide present in the 111.30 (10,9,8,7,6,15) 1.53 (5,16) 1.73 142.75 (17) 3.28 (12,4) solution the peak should have had the integral of 2; however, from the integral of 1.72, we can determine that around 80% of the product is related to amide and the rest is excess octylamine. Details of peak assignments and integrations are given in the legend of Figure 8.…”

“…Metal oxide-based nanoparticles (NPs) are among the most commercially important nanoparticles with a wide range of applications, including fillers [1], preceramic materials allowing for controlled morphology and porosity [2,3], biological and biomedical applications [4][5][6][7][8][9][10], organic based electronic devices [11], coatings [12], water purification membranes [13][14][15][16][17], and enhanced oil recovery (EOR) [18,19]. To use oxide NPs in most of these applications, the particles need to be combined with organic moieties (resins, polymers, acids, etc.)…”

Facet-Specific Assembly of Proteins on SrTiO3 Polyhedral Nanocrystals

“…Polyethylene oxide-functionalized carbon nanotube-based biosensors have been used for selective recognition of target proteins10. In recent years, considerable efforts have been put into understanding the distribution of reacted sites for protein adsorption111213. However, how to precisely and selectively engineer protein to a specific site is still a challenge.…”

Isolation methods for particle protein corona complexes from protein-rich matrices

“…3,[56][57][58] Even though most studies have the analysis of particle-protein interactions in common, very different aspects related to protein adsorption and corona formation are investigated. For example, some studies focus on the relationship between particle properties like surface chemistry and protein corona formation 14,23,[59][60][61][62][63][64][65] and others analyze the protein corona as particle properties (like size or shape) needed to interpret cellular or biological effects. 26,38,[66][67][68][69][70][71][72] Further aspects include improving particle properties to change protein corona composition and biological response; [73][74][75] targeting or characterizing of particles for usage as drug carriers or for other medical purposes; [76][77][78][79][80][81] or the comparison of different particles.…”
