Formulation of Iron Oxide Nanoparticle Suspensions for FUS/MRI Applications
Focused ultrasound combined with magnetic resonance imaging (FUS/MRI) is a promising approach for noninvasive therapy that requires precise imaging of tissue using MRI to guide the FUS process. The MRI suffers from interference from water baths commonly used to transmit the focused ultrasound waves from a transmitter to the tissue. In this work, iron...

An Assistive Robotic Exoskeleton Glove Designed for Patients with
Brachial Plexus Injuries
THE CHALLENGE
Exoskeleton gloves have proven to be invaluable in post-surgery therapy for patients with Brachial Plexus Injuries, countering hand muscle atrophy through controlled and assisted movements. While many rehab gloves target stroke recovery, they lack the desired Human-Machine Interface and struggle to find the right balance between performance...

New process for selective polysaccharide derivative oxidation
THE CHALLENGE
Aqueous solubility and controllable release are essential for bioactive compounds. In the case of oral drug delivery, poor aqueous solubility of a drug can lead to low bioavailability. For poorly bioavailable drugs, higher doses are required to achieve a therapeutic concentration in systemic circulation. This can in turn have negative...

Novel Production Method of Stink Bug Pheromone
for Crop Protection
THE CHALLENGE
In integrated pest management, synthetic pheromones are often deployed in traps or with trap crops to lure insects away from commercial crops. Currently these pheromones are chemically synthesized and applied to trap crops. This form of production has limited sustainability and there are difficulties with high yield production. Therefore,...
