This work encompasses three individual projects concerning biomaterials and their modifications. Chemically-Induced Cross-Linking of Peptidic Fibrils for Scaffolding Polymeric Particles and Macrophages EAK16-II (EAK) is a self-assembling peptide (SAP) that forms β-sheets and βfibrils through ionic-complementary interactions at physiological ionic strengths. The soft materials can be injected in vivo, creating depots of drugs and cells for rendering pharmacological and biological actions. The scope of the applications of EAK is sought to extend to tissues through which the flow of extracellular fluid tends to be limited. In such anatomical locales the rate and extent of the fibrilization are limited insofar as …

Makara Journal of Science
Gellan gum (GG) has gained considerable attention in the food, chemical, and pharmaceutical industries due to its functional characteristics. It has versatile properties, such as water solubility, easy bio-fabrication, good film/hydrogel-formation, biodegradability, and biocompatibility. These properties render GG a promising material in biomedical applications, specifically in the development of wound dressing materials. In this review, the use of GG biopolymer as a wound dressing material was discussed. Various fillers, such as titanium dioxides, clay, drug, and honey, have been incorporated in GG to produce film, hydrogel, or scaffold materials. The effects of filler on the mechanical performance, physical properties, antibacterial …

The synthesis of a highly conductive, flexible, 3D-printable, and biocompatible ink has been of great interest in the field of bio-based additive manufacturing. Various applications include ultra-sensitive, microscale tactile sensors, patient-customizable scaffolds for cardiac and nerve tissue regeneration, and flexible electrocardiogram (ECG) electrodes. Here, a novel elastomeric carbon nanocomposite is presented consisting of amino-functionalized carbon nanotubes (CNT-NH2) homogenously dispersed in a one-part room-temperature vulcanizing (RTV) silicone matrix. The use of acetone as a swelling solvent aids in electrical percolation through the elastomer matrix. CNT-NH2 ratios can be tuned to fit various needs; higher tensile strength is favored …
