Cellulose/vaterite nanocomposites: Sonochemical synthesis, characterization, and their application in protein adsorption

Modification of Surfaces with Vaterite CaCO3 Particles

“…Cellulose and vaterite nanocomposite materials have excellent cytotoxicity, along with an elevated protein adsorption capacity—ideal for local drug delivery and tissue engineering applications. Results have shown that calcium ions adsorb to the hydroxyl groups along the cellulose backbone; carboxylic groups present on the surface of cellulose also contribute by accumulating calcium ions, leading to the nucleation of CaCO 3 polymorphs and crystal growth [ 17 ] ( Figure 3 ).…”

“…When the concentration of cellulose was increased to 4.05 and 8.10 mg/mL, there was a binding of vaterite onto cellulose, no individual vaterite crystals and calcite formation was suppressed ( Figure 4 e,f). The image F-2 shows that rice-shaped nanoparticles are formed from vaterite nanospheres [ 17 ].…”

“…Its vaterite form is more beneficial for research purposes due to its wide range of applications [ 14 ]; owing to its inherent biocompatibility and biodegradability [ 7 ], as well as the capacity to host large amounts of bioactive compounds due to its mesoporosity [ 15 , 16 ]. Hence, the synthesis of vaterite with controlled size and morphology is recently a major field of interest [ 17 ] and will be the polymorph of focus for this review. It is worth mentioning the immobilization of other polymorphs is of great interest, but this topic is out of the scope of this review and will be considered in our future research.…”

Calcium carbonate particles: synthesis, temperature and time influence on the size, shape, phase, and their impact on cell hydroxyapatite formation

“…11 Aragonite is more challenging to produce, and its applications are usually focused on paleogeological research. 12,13 The third type -vaterite -is more interesting with respect to applications in biomedical fields, such as protein adsorption, 14 targeted 14 and extended drug delivery, 15 thermochemotherapy, 16 photodynamic therapy, 17 selective adsorption, and the separation of toxic dyes from wastewater. 18 According to the Ostwald-Lussac rule for the stages of a supersaturated solution with more than one mineral, the initially formed mineral has the highest solubility.…”

Tropine‐Based Ionic Liquid Gel for Adsorption of Protein Ovalbumin: High Capacity, Selectivity and Biocompatibility

“…To find out the role of protein in the body, simulation experiments in vitro are often to be made, which requires separating and purifying of protein samples. Further, the separation and purification methods of proteins include salting-out method, [1] ultrafiltration technology, [2] adsorption method, [3] etc. Adsorption is highly appreciated because it's easy to operate, and normally has mild conditions and simple equipment.…”
