New Taipei City Urban Science Festival - '2023 New Taipei Science Day - Golden Nana'/ Recovering gold from rapid screening test strips in New Taipei Science Day 2023. We will recover nanogold from the rapid screening test strips in home-based COVID-19 antigen self-test kits (nasal swabs), and synthesize solutions of different colors using nanogold as a template.

Use the fast screen reagent to connect, and understand the actual application of nano technology in daily life, allow teachers and students to learn about the relevant knowledge of nano technology, and use silver metal materials to be stacked on the nano -level gold surface. The rice structure, as a nano structure that simulates the color of the biology, is used to absorb a filter with specific colors. This course is imagined on the red "nano gold" lines on the fast screen reagent. Students do experiments and recycle nano -gold, reflecting the responsibility consumption of sustainable development goals (SDGS). The recovered gold can also be reused. As a catalyst and nano -level electrodes. At the same time, nanomallic gold can be used as a crystal species, which can be prepared into a colorful nano solution. An established idea. Students do experiments together, observe the color sign in the antigen fast screen test agent, and explore the principle of nano gold discoloration. It is also invited to adapt the popular popular science "Journey to the West", the funny role and magical experimental performance, so that students can call directly. The original science is in life!
