Control System Development for a Gastric Retention and Injection Device for Autonomous Urgent Care Therapy

Time-sensitive medical emergencies resulting from the entry of harmful agents into the body require immediate and urgent medical attention to prevent irreversible symptoms or fatalities. However, the current process for urgent care relies on human intervention, which can introduce significant delays and potentially compromise the effectiveness...

A robust material for the production of microfluidic liquid-liquid extraction chips: Evaluation of a robust ALD coating to reduce irradiation-induced surface modifications on polymers and quartz for the usage of microfluidic liquid-liquid extraction chips

Microfluidic extraction is a promising alternative for existing extraction methods of radioisotopes due to the high surface-to-volume ratio. When assessing the compatibility of microfluidic material with the extraction system, there are three critical aspects—compatibility with organic solvents, compatibility with the radiochemistry, and, most...

Gamma Radiation Induced Contraction of Alkyne Modified Polymer Hydrogels

Gamma radiation triggered secondary crosslinking of dextran hydrogels leads to macroscopic hydrogel contraction. The authors use stable polymer hydrogels, prepared through azide-alkyne crosslinking, containing surplus alkyne groups. γ-irradiation of these gels leads to more alkyne crosslinking, enabling controlled increase of crosslink...

Playing hard to catch: Seeing more with less (radiation)

X-ray and gamma radiation are widely used in hospitals and laboratories, and in the manufacturing and mining industries. Several methods exist for making the radiation "visible", including scintillators, films, and semiconductor materials. Scintillators are crystals that convert ionising radiation into visible light. This is a field in which...
