Identifying Suitable Three-Dimensional Bio-Printed Scaffold Architectures to Incubate in a Perfusion Bioreactor: Simulation and Experimental Approaches
(The American Society of Mechanical Engineers (ASME), 5/15/2023 )Traditional cell culturing methods are limited in their ability to supply growth medium to cells within scaffolds. To address this, we developed a custom perfusion bioreactor that allows for dynamic medium supply to ... -
Designing an Interchangeable Multi-Material Nozzle System for the Three-Dimensional Bioprinting Process
(The American Society of Mechanical Engineers (ASME), 3/8/2023 1)Three-dimensional bioprinting is a rapidly growing field attempting to recreate functional tissues for medical and pharmaceutical purposes. Development of functional tissue requires deposition of multiple biomaterials ... -
Comparative Efficacy of Humidifiers for Noninvasive Infant Respiratory Support
(The American Society of Mechanical Engineers (ASME), 1/31/2023 )Delivery of cold, dry air to infants while supporting their breathing can lead to hypothermia in addition to irritating and damaging their sensitive nares and negatively impacting outcomes with these therapies. In high ... -
Development of an Endotracheal Tube Cap for Oxygen Delivery During Intubation
(The American Society of Mechanical Engineers (ASME), 2023)Endotracheal (ET) Intubation is a medical procedure whereupon a physician or trained personnel inserts a breathing tube into a patient's mouth, through their vocal cords, and into their trachea. Intubation can be lifesaving ... -
Novel Bilayer Elasto-Hydrogel Adhesive Film for Facilitating Wet-Occlusive Therapy for Atopic Dermatitis
(The American Society of Mechanical Engineers (ASME), 2023)Atopic dermatitis (AD) is a common chronic multifactorial skin disease that causes skin inflammation owing to defects in the skin barrier, immune dysregulation, or infectious agents. The most common treatment of AD utilizes ... -
