Near-IR activated, violet/blue-emitting adhesive liner containing 2-photon, up-converting nanoparticles for dental bonded restorations

Current State of the Art In dental bonded restoration technique, a methacrylate-based semi-viscous agent (liner) is placed on the prepared tooth structure. This liner is exposed to blue or violet light, which enables the liner to bond to the tooth. Following this, the missing tooth structure is filled with glass-filled composite, the top of which is...

Tissue Chip Bioreactor for Tissue Engineering

Researchers at AU developed a full-scale prototype of a bioreactor for growing complex tissues in a scalable manner. This bioreactor chip can yield several mm tissues consisting of different cell types. Apart from tissue transplants it can also be used for high-throughput tissue engineering and pre-clinical replacement for animal models.
