Abstract Scope |
Biomimetic structures act as building blocks for biomedical engineering. Learning more about these structures will improve our understanding on how to apply these structures for various bio-medical applications. In this study, innovative biomimetic structures were generated using layer-by-layer self-assembly. Various chemical combinations including poly-L-lysine (PLL)/poly-L-glutamic acid (PLGA) coatings and PLL/poly sodium 4-styrenesulfonate (PSS) coatings were studied. These coatings were formed based on electrostatic interactions. Various substrate materials such as stainless steel, quartz, and glass were used to prepare the biomimetic structures. Each substrate was dipped into the chemical solution for 15 minutes rinsed with deionized water, and then air dried before being placed into the next solution, rinsed, and dried. This process was repeated for forty cycles to create the biomimetic structures. The self-assembly process was carried out manually. A robotic machine was also used to increase production. The produced biomimetic structures were imaged using a scanning electronic microscope. |
