Biological drugs generated via recombinant techniques are uniquely positioned due to their high potency and high selectivity of action. The major drawback of this class of therapeutics, however, is their poor stability upon oral administration and during subsequent circulation. As a result, biological drugs have very low bioavailability and short therapeutic half-lives. Fortunately, tools of chemistry and biotechnology have been developed into an elaborate arsenal, which can be applied to...

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...

Background: Quince seed mucilage biopolymer (QSMB), famous for ameliorating coughs and controlling asthma symptoms, has not been processed by scientific methods and rules into a local oral tablet. Objectives: The purpose of this study was to investigate and compare the mechanical properties of QSMB with different size fractions of the mucilage powder, dried by oven or by freeze drying, to achieve a tablet. Materials and Methods: The granules dried by oven and freezing processes were classified...

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
