This protocol describes a method for encapsulating DNA into amorphous silica (glass) spheres, mimicking the protection of nucleic acids within ancient fossils. In this approach, DNA encapsulation is ...

In cell encapsulation, transplanted cells are protected from immune rejection by an artificial, semipermeable membrane, potentially allowing transplantation (allo- or xenotransplantation) without the ...

The clay montmorillonite is known to catalyze the polymerization of RNA from activated ribonucleotides. Here we report that montmorillonite accelerates the spontaneous conversion of fatty acid ...
