PLA porous microneedles: rapid detection of covid-19 antibody.07 06,2022
Japanese researchers have developed a new antibody based method for rapid and reliable detection of novel coronavirus without the need for blood samples. The research results were recently published in the journal Science report. After proving that interstitial fluid may be suitable for antibody detection, researchers developed an innovative method of sampling and testing. First, researchers developed biodegradable porous microneedles made of polylactic acid, which can extract interstitial fluid from human skin. Then, they constructed a paper-based immunoassay biosensor to detect covid-19 specific antibodies. By integrating these two elements, the researchers created a compact patch that can detect antibodies on site in 3 minutes.

In 2025, Apple will eliminate all plastics in packaging.07 06,2022
On June 29, at the ESG global leaders summit, Ge Yue, managing director of Apple Greater China, delivered a speech saying that Apple has achieved carbon neutrality in its own operating emissions, and promised to achieve carbon neutrality in the whole product life cycle by 2030. Ge Yue also said that Apple has set the goal of eliminating all plastic packaging by 2025. In iPhone 13, no plastic packaging parts are used anymore. In addition, the screen protector in the packaging is also made of recycled fiber. Apple has kept the mission of environmental protection in mind and taken the initiative to assume social responsibility over the years.

Polylactic acid has achieved remarkable results in desertification control!07 01,2022
In view of the problems that the vegetation on the exposed wound surface of severely desertified grassland is scarce and the plant seeds cannot be fixed, the project has developed the "hybrid technology of mechanical sand barrier and biological sand fixation of new materials for rapid treatment of severely desertified grassland". This technology uses long sandbags made of low-cost and easy-to-operate biodegradable polylactic acid materials to set up a grid type mechanical sand barrier, combined with the sowing technology of Artemisia ordosica seeds in the sand barrier, It solves the problem of fixing seeds on quicksand and can be used for rapid restoration of severely sandy grassland.

Implemented in December! Canada issues the "plastic ban" regulation!07 01,2022
Steven Guilbeault, the Federal Minister of environment and climate change, and Jean Yves Duclos, the Minister of health, jointly announced that the plastics targeted by the plastic ban include shopping bags, tableware, catering containers, ring portable packaging, mixing rods and most straws. From the end of 2022, Canada officially banned companies from importing or producing plastic bags and takeout boxes; From the end of 2023, these plastic products will no longer be sold in China; By the end of 2025, not only will it not be produced or imported, but all these plastic products in Canada will not be exported to other places!
