Abstract: The present invention relates to a gene gun and the application of the gene gun for gene transformation. A low pressure gas is used in the gene gun to directly accelerate the biological material containing solution, so that the biological materials penetrate through the cell membrane/wall or the skin of an animal, without using metal particle carriers, for gene transformation.

Abstract: The present invention provides an apparatus and method for attracting mosquitoes by using the microbe product as the mosquito bait as well as simulating the human emanated odors. A bait-releasing unit/means is included to enhance the release of the mosquito bait. A well-controlled heating assembly can be used to generate a suitable thermal gradient for simulating body temperature and evaporating the bait. The microbe product comprises at least a sterilized supernatant of a bacterial incubation product. The apparatus of this invention can further include electrocution grids or insecticide webs to destroy attracted mosquitoes.

Abstract: The present invention provides a method and apparatus for generating the mosquito bait as well as stimulating the human body's surface temperature and emanated odor. A well-controlled heating assembly can be used to generate a suitable thermal gradient for simulating body temperature and evaporating the bait. The bait comprises at least the bacterial fermentation product. The bait is not poisonous to human beings and contains mosquito attractants made from natural products of fermentation or decomposition. The apparatus according to this invention comprises at least an upper compartment for trapping mosquitoes and a bottom compartment including the bait and the beating assembly. This invention can also combine with electrocution grids or insecticide webs to destroy attracted mosquitoes.

Abstract: The present invention provides a method and apparatus for generating the mosquito bait as well as simulating the human body's surface temperature and emanated odor. A well-controlled heating assembly can be used to generate a suitable thermal gradient for incubating both microorganisms and evaporating the bait. A bait-releasing unit is used to enhance the release of the mosquito bait. The bait comprises at least the bacterial decomposition and the yeast fermentation solution. The bait is not poisonous to human beings and produces mosquito attractants from natural products of fermentation or decomposition. The apparatus according to this invention comprises at least an upper compartment for trapping mosquitoes and a bottom compartment including the bait and the heating assembly. This invention can also combine with electrocution grids or insecticide webs to destroy attracted mosquitoes.

Abstract: A gene gun is described wherein the contour design of the spray nozzle of the gene gun modifies the operation of the gene gun. A low pressure gas is used to accelerate the micro-particles that are coated with nucleic acid of a foreign gene into cytoplasma or nuclei of an animal or plant cell to express the special protein and to generate the new biological function.
