Title: Innovations of Pengwei Li in Biotechnology and Imaging

Introduction

Pengwei Li is a notable inventor based in Beijing, China, recognized for his contributions to biotechnology and imaging technologies. He holds two patents that showcase his innovative approaches in these fields. His work not only advances scientific understanding but also has practical applications in agriculture and imaging.

Latest Patents

One of Pengwei Li's latest patents is a transgenic method of obtaining blue flowers by catalyzing glutamine to synthesize indigo. This method involves cloning a Sfp gene and a bpsA gene into a plant-promoter-containing plasmid, followed by amplifying the plasmid and transferring it into a plant. The resulting blue flowers exhibit characteristics similar to natural flowers, including freshness, fragrance, and non-toxicity. The transgene-encoded enzyme and produced indigo remain unaffected by the plant's vacuole pH, ensuring a pure blue color. The substrate for this enzyme, glutamine, is abundant in plants, making this method efficient and sustainable.

Another significant patent by Pengwei Li is related to a polarization imaging apparatus, method, controller, and storage medium. This apparatus includes an optical rotation device, lens device, image sensor, and image processor, all arranged to optimize the collection of polarized image information. The controller manages the optical rotation and focus states, allowing for the acquisition of multiple images that enhance the quality of polarized imaging.
