Abstract This review summarizes recent progress of the robust and smart hydrogels prepared from natural polymers including polysaccharides, proteins, etc. These hydrogels exhibit outstanding mechanical properties due to their nanofibrous aggregated microstructures and special crosslinking networks. Furthermore, these hydrogels show some smart stimuli-responsive behaviors triggered by pH, temperature, light, electricity and magnetism. Hopefully, these hydrogels derived from natural polymers with...

Abstract The aim of this review is to draw attention on potential applications of phospholipids in drug delivery system through different sources, structure, properties and as carrier. Phospholipids have the exceptional biocompatibility and remarkable amphiphilicity characteristics that make phospholipids the major and suitable agent or excipient for the formulation and to achieve better therapeutic applications in drug delivery system. The applications of phospholipids in the drug delivery...

Abstract Bio-nanocomposites, composed of biopolymers and inorganic solids, show dimensions in the nanometer range (1–100 nm) which can be widely used in variety of areas owing to multidimensional properties like biocompatibility, antimicrobial activity and biodegradability. Considering these versatile properties of the bio-nanocomposites this review sheds a light on the synthesis, modification, characterization and applications of bio-nanocomposites based on different polysaccharides...

Introduction: With continual focus on oral drug delivery systems (ODDS), the role of freeze-drying becomes increasingly valuable. While freeze-drying is fundamentally a desiccation process, the advantageous material properties attributed to freeze-drying extend far beyond the preparation of stable pharmaceutical products. The formulation and process variables are important considerations as they affect the final freeze-dried product characteristics. It is of interest to expound on the...

Novel hydroxypropylmethyl cellulose (HPMC)-based sponges containing self-microemulsifying curcumin (SME-Cur) were prepared by a freeze drying method using different grades of HPMC (E5 LV, E15 LV, E50 LV, A15 LV, and A4C). The physical properties and drug release from these carriers were characterized and compared among the different formulations. The mean pore size values of the sponges from image analysis ranged from 43.36 ± 4.54 to 123.22 ± 8.19 nm. More
