A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

open access: yesAdvanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.

Water‐Soluble, Enzyme‐Degradable, and Hydrolyzable STAR Particles for Enhanced Drug Delivery to Skin

open access: yesAdvanced Healthcare Materials, EarlyView.
Biodegradable polymer STAR particles fabricated from water‐soluble, enzyme‐degradable, and hydrolyzable materials significantly enhance intradermal drug delivery. By replacing conventional non‐biodegradable materials, these STAR particles address environmental and safety concerns while expanding the potential of skin‐based drug delivery technologies ...

Making the Case for Organ‐on‐Chip Platforms in Long‐Acting Therapeutics Development

open access: yesAdvanced Healthcare Materials, EarlyView.
LATs release drug from a tissue‐resident depot over weeks to months, improving adherence, but their development is hampered by preclinical models that cannot reproduce the coupled tissue processes, sustained release, local microenvironment change, interstitial transport, immune and foreign‐body responses, and clearance that govern depot performance in ...

Geophysical investigations at ORNL solid waste storage area 3

open access: yes, 1985
Geophysical investigations at ORNL solid waste storage area 3 have been carried out. The investigations included very-low-frequency-electromagnetic resistivity (VLF-EM), electrical resistivity, and seismic refraction surveys. The surveys resulted in the measurement of basic geophysical rock properties, as well as information on the depth of weathering ...
