Additive manufacturing of PLA/HNT nanocomposites for biomedical applications
Venkatesh, Chaitra; Fuenmayor, Evert; Doran, Patrick; Major, Ian (Elsevier, 2019)Additive manufacturing has been of great interest of research in various applications due to their ease in processability, cost effectiveness and adaptability. In this study Poly Lactic Acid (PLA) was used as the base ... -
Biodegradation and antimicrobial properties of zinc oxide-polymer composite materials for urinary stent applications
Venkatesh, Chaitra; Laurenti, Marco; Bandeira, Marina; Lanzagorta, Eduardo; Lucherini, Lorenzo; Cauda, Valentina; Devine, Declan M. (MDPI, 2020-10-20)Research advancements in the field of urinary stents have mainly been in the selection of materials and coatings to address commonly faced problems of encrustation and bacterial adhesion. In this study, polylactic acid ... -
Development of drug eluting biodegradable nanocomposite for use in coronary stents
Venkatesh, Chaitra (Athlone Institute of Technology, 2021-07)Coronary stents are the scaffolds placed inside the blocked arteries, which aids the restoration of the passage of blood to the heart. Coronary stenting has become a standard medical procedure to treat coronary heart disease ... -
Development of high strength nanocomposite for biodegradable stents
Venkatesh, Chaitra; Chen, Yuanyuan; Cao, Zhi; Brennan, Shane; Major, Ian; Lyons, John G.; Devine, Declan M. (Athlone Institute of Technology, 2018-04-24)The use of biodegradable polymer materials are considered to be good alternatives in urology (Donohue et. al. 2018), cardiovascular (Brie et. al. 2016) and tracheal airway stenosis which provide support before it is absorbed ... -
Faster release of lumen-loaded drugs than matrix-loaded equivalent in polylactic acid/halloysite nanotubes.
Venkatesh, Chaitra; Clear, Oran; Lyons, John G.; Devine, Declan M.; Faster release of lumen (MDPI, 2019-06-15)Nanocomposite-based drug delivery systems with intrinsic controlled release properties are of great interest in biomedical applications. We report a novel polylactic acid (PLA)/halloysite nanotube (HNT) nanocomposite-based ... -
