Two-dimensional materials, particularly graphene-based materials, having a plurality of apertures therein can be formed into enclosures for various substances and a fibrous layer can be provided on an outside and/or on an inside of the enclosure. The enclosures can be exposed to an environment, such as a biological environment (in vivo or in vitro), where the fibrous layer can promote vascular ingrowth. One or more substances within the enclosure can be released into the environment, one or more selected substances from the environment can enter the enclosure, one or more selected substances from the environment can be prevented from entering the enclosure, one or more selected substances can be retained within the enclosure, or combinations thereof. The enclosure can, for example, allow a sense-response paradigm to be realized. The enclosure can, for example, provide immunoisolation for materials, such as living cells, retained therein. |
