Prof. Dr. Aqil Nazzal Barbar and Assistant Prof. Dr. Ali Abdul-Hussein Karim from the College of Agriculture at the University of Karbala obtained a patent for enabling them to manufacture a new device for delivering DNA plasmids into plant tissues using particles as an alternative to gold particles. The patent included the manufacture of a local device (Homemade particle delivery system) to release particles covered with DNA plasmids and deliver them into plant cells with efficiency similar to devices manufactured by specialized companies to produce genetically modified plants or transgenic plants that carry genetic characteristics. New.The patent aims to use the manufactured device in laboratories and fields without the need for an electric source when working in a place far from the presence of an electric current source, as the device is equipped with a rechargeable battery, which facilitates the operation of the air compressor and maintains the pressure required for the success of the vaccination process. without the need for a direct source of electric current. The device proved the possibility of using fine and sterilized glass particles after covering them with DNA plasmids and delivering them to plant cells, which were distinguished by their ease of preparation, use, and abundant availability without the need to purchase them, and as an alternative to the expensive gold particles, whose value is estimated at (187 USD). / 10 mg) as well as difficult to obtain.In this device, normal compressed air was used as an alternative to helium gas, which is used in the devices manufactured by these companies, in addition to that the manufactured device is characterized by its low weight, small size and ease of use, which makes it easier to transport and use compared to the size, weight and abundance The accessories of previously manufactured and commonly used devices, and its simple components with a cost that does not exceed 300 US dollars, compared to devices manufactured by specialized companies, whose prices reach 17,000 US dollars.
