Application


  • Chitosan-PVA-PVP/nano-clay composite: a promising tool for controlled drug delivery.: This study explores the development of a composite material using chitosan, PVA, PVP, and potassium phosphate dibasic for controlled drug delivery. The composite demonstrates enhanced drug encapsulation and release properties, making it suitable for pharmaceutical applications (Ali et al., 2024).

  • Biocatalysis with in-situ product removal improves p-coumaric acid production.: This research investigates the use of potassium phosphate dibasic in biocatalytic processes for the production of p-coumaric acid. The study highlights the efficiency of in-situ product removal techniques to enhance production yields in biochemistry applications (Virklund et al., 2024).

  • Partitioning recombinant chitinase from Nicotiana benthamiana by an aqueous two-phase system based on polyethylene glycol and phosphate salts.: This research employs potassium phosphate dibasic in an aqueous two-phase system for the extraction and purification of recombinant chitinase. The study demonstrates the effectiveness of this method in biotechnological applications (Tue et al., 2024).
