Abstract (en)

[origin: WO9417195A1] An improvement in the process of transporting biological materials into living cells by bombarding the cells with microprojectile particles coated with biological material. In the improved process prior to coating of the particles such as tungsten beads for example, with biological material such as DNA, the particles are first pretreated with a strong inorganic acid such as nitric acid.
