Abstract: Systems and methods are provided for comprehensive in vivo nanotoxicity testing, as well as fabrication methods of chips used for nanotoxicity testing. A three-dimensional (3D)-printed, automated microfluidic chip can be configured for in vivo nanotoxicity testing, and the chip can allow for multi-route (e.g., waterborne and/or foodborne) exposure of marine organisms to small materials (e.g., plastics such as microplastics and/or nanoplastics (NPLs), or metals), providing real-time, in situ monitoring of bioaccumulation and oxygen consumption.

Abstract: Foams and methods of fabricating and using the same are provided. The foams can be free-standing and rigid and can be used as, for example, nanofiller networks. The shape and size of the foam pore interconnected network can be tailorable/tailored. The foams can be, for example, transition metal dichalcogenide (TMD) foams with a layered structure (e.g., tungsten sulfide (WS2) foams). A freeze-drying-based method can be used to fabricate bulk porous foam, which can be used for, e.g., polymer nanocomposites. A vacuum-assisted infiltration procedure can be used to fabricate a foam-polymer nanocomposite.
