Gas-Foamed Scaffold Gradients for Combinatorial Screening in 3D

Gas-Foamed Scaffold Gradients for CombinatorialScreening in 3D

Current methods for screening cell-material interactions typically utilize a two-dimensional (2D) culture format where cells are cultured on flat surfaces. However, there is a need for combinatorial and high-throughput screening methods to systematically screen cell-biomaterial interactions in three-dimensional (3D) tissue scaffolds for tissue engineering. Previously, we developed a two-syringe...

Designing a gas foamed scaffold for keratoprosthesis.

Artificial corneas or keratoprostheses are intended to replace diseased or damaged cornea in the event that vision cannot be restored using donor cornea tissue. A new class of artificial cornea comprising a combination of poly (2-hydroxyethyl methacrylate) and poly (methyl methacrylate) was developed which was fabricated using a gas foaming technique. Referred to as the gas-foamed KPro, it was ...

Decellularized kidney in the presence of chondroitin sulfate as a natural 3D scaffold for stem cells

Objective(s): Use of biological scaffolds and automating the cells directing process with materials such as growth factors and glycosaminoglycans (GAGs) in a certain path may have beneficial effects in tissue engineering and regenerative medicine in future. In this research, chondroitin sulfate sodium was used for impregnation of the scaffolds. It is a critical component in extracellular matrix...

Sulfophenyl-Functionalized Reduced Graphene Oxide Networks on Electrospun 3D Scaffold for Ultrasensitive NO2 Gas Sensor

Ultrasensitive room temperature real-time NO₂ sensors are highly desirable due to potential threats on environmental security and personal respiratory. Traditional NO₂ gas sensors with highly operated temperatures (200-600 °C) and limited reversibility are mainly constructed from semiconducting oxide-deposited ceramic tubes or inter-finger probes. Herein, we report the functionalized graphene n...
