Artificial cells mimic the natural cell-aware environment

Synthetic biologists have long had high hopes for artificial cellsRelatively complex artificial cells are more environmentally sensitive than generally simple synthetic structures and can perform a variety of tasks, such as delivering drugs, tracking cancer cells, detecting toxic chemicals, and improving diagnostic accuracyHowever, natural cells themselves have the ability to respond to external chemical changes, a complex process that makes it difficult to precisely regulate artificially designed cell "replicas", which has long been seen as an engineering challenge, the Imperial College team successfully completed the experiment: they cultured new artificial cells that can sense and react to chemical signals outside the cells by activating an artificial signaling pathway inside the cellThe results showed that these artificial cells were able to sense changes in calcium ions and show their reactions to them in the form of luminescenceThe process by which the artificial cells react to chemical changes is much simpler than that of natural cells, making it easier for scientists to regulate themJames Newdale, of Imperial College, astudy, said artificial cells now have good application prospects, for example, in the future to create artificial cells that can sense tumor markers and synthesize drugs in the body, or they can be developed that can sense dangerous heavy metals in the environment while releasing spongy material to remove themeditor-in-chiefscientists have made a lot of success in this area when people ask on social networking sites if it is possible to synthesize artificial cells in the labIn 2016, the team of renowned biologist Craig Venter claimed to have designed the simplest artificial cells of the time, using only 473 genesIn 2018, scientists announced the synthesis of the most realistic artificial cells of the timeHowever, the function and characteristics of natural cells have evolved in a long history, and it is still a long process of research and development to achieve artificial cells and natural cells.
