Modification of PLA Scaffold Surface for Medical Applications
نویسندگان
چکیده
Materials used for medical applications (e.g., the cellular scaffold) should have not only specific chemical composition, but surface layer properties as well. For this reason, a method which enables an increase in number of pores, wettability surface, and improvement conditions nutrient transportation into membrane is being studied. The plasma dielectric barrier discharge was applied modification polylactide obtained by dry or wet phase inversion. plasma-modified analyzed contact angle measurements with water diiodomethane. free energy (SFE) calculated Owens–Wendt method. highest SFE its polar component (67.6 mJ/m2 39.5 mJ/m2, respectively) were received when process conducted Ar + CO2 gas mixture power 20 W. purpose research to porosity membrane’s surface. It can be concluded that effectively change membranes, structure modified membranes damaged during modification. easier made These materials had higher values after

Biodegradable Polylactic Acid (PLA) Microstructures for Scaffold Applications
In this research, we present a simple and cost effective soft lithographic process to fabricate PLA scaffolds for tissue engineering. In which, the negative photoresist JSR THB-120N was spun on a glass subtract followed by conventional UV lithographic processes to fabricate the master to cast the PDMS elastomeric mold. A thin poly(vinyl alcohol) (PVA) layer was used as a mode release such that ...

Applications of gold nanoparticles for medical imaging
Background & Aim: Molecular imaging enables us to non-invasively visualize tissue microstructures and lesion characterization, allowing accurate diagnosis of diseases at early stages. A successful molecular imaging requires a nontoxic contrast agent with high sensitivity. Nowadays, a wide range of nanoparticles have been developed as contrast agents for medical imaging modalities. Here, we revi...
