This review concentrates on how artificial cells can contribute to helping patients with COVID-19. Artificial cells have led to mRNA vaccines with more improvements to come. Excessive cytokines in severe COVID-19 can damage organs leading to death. Artificial cell-based collodion macroporous activated charcoal adsorbent can effectively remove middle molecular weight range molecules in patients. A novel hemoperfusion device based on collodion membrane macroporous synthetic resin effectively removes cytokines and recovery in COVID-19 patients. This has been approved as an emergency treatment for COVID-19 in China, Europe, and Canada. A recent nanobiotherapeutic containing haemoglobin and up to six times the concentration of red blood cell enzymes: catalase, superoxide dismutase and carbonic anhydrase. In an animal study, this can effectively lower the damaging increase in free radicals and the removal of increased tissue pCO2. This can also help as blood substitute for the severe and critical problem of COVID-19 pandemic donor blood supply crisis.KEY MESSAGESCOVID-19 and its variants have resulted in major pandemics, severe sicknesses, and deaths around the world. COVID-19 and its variants has only started less than 3 years ago, and it is even more recently that we know more about its mechanisms, requirements, prevention, and treatment. This being the case, this is the first review on the present status and future perspectives of the use of the principle of artificial cells for COVID-19 related to vaccines, treatment, and critical donor blood supply shortage.
