Exploration of Inbuilt Novel Properties as Bioretardant Cum Stabilizer of Isolated Biopolymer ...

The research aims to develop bionanosuspension using a biopolymer isolated from Fragaria ananassa fruit that constitutes potential and natural polymeric properties. At first, the biomaterial was isolated from the natural fruit pulp of Fragaria ananassa by an economical method of isolation. The model drug was nanosized by a novel sonication method. The isolated biopolymer was characterized for its polymeric properties, and its potential capabilities were evaluated in the delivery of nanosized phenytoin. The isolated biopolymer was characterized for DSC, FTIR, NMR, mass, and scanning electron microscopy. The isolated biomaterial was used for the preparation of phenytoin-loaded bionanosuspension with other excipients. The bionanoparticles were also characterized by different analytical testing such as FTIR, DSC, and SEM to confirm any interaction between model drug and biopolymer. The prepared bionanoparticles showed the release of phenytoin in a sustained manner over 36 hours. The release kinetic study was done using the BIT-SOFT 1.12 software and other parameters such as t50%, t80%, and r2 were calculated. The formulation PFr6 was considered best having t50% in 18.22 hours and t80% in 29.62 h with an r2 value of 0.9793. This formulation showed up to 87.89% drug release within 36 hours. The prepared bio-nanosuspension was found to be stable and in a well-dispersed state. The dried bionanosuspension evaluation revealed no interaction between model drug and biopolymer without any...
