Solution:

A gene gun or a biolistic particle delivery system, originally designed for plant transformation, is a device for injecting cells with genetic information. The payload is an elemental particle of a heavy metal coated with plasmid DNA. Millions of DNA-coated metal particles called microprojectiles are shot at target cells or tissues using a biolistic device or gene gun.
