Artificial blood could become a reality?

Participating in the global race to find a replacement blood, British scientists have suggested considering a global patent for the type of hemoglobin, the key ingredient in their blood. .

The work of the Twilight trio refers to 'vegetarian' vampires, living with animal blood. And on True Blood TV series, Japanese scientists have developed a synthetic blood type. However, in the latest blockbuster Daybreakers, vampires have suffered a terrible fate when trying to drink a blood substitute.

Back in the real world, hunting for a blood substitute might not be reliable. In fact, the search to create an artificial blood is a major commercial issue. More than a billion pounds has been used for this purpose over the past 20 years in an effort to create a substance that can actually replace blood.

Participating in this global search are scientists from Essex University, England. They submitted a review to obtain a global patent for their hemoglobin.

More than 75 million units of donated blood are used in hospitals for the treatment of human illnesses worldwide. However, the need for blood transfusions for daily surgeries is increasing.

A true blood substitute would be extremely useful if it could be preserved long-term, stored outside hospitals, without consideration of blood-group harmony and ensuring no infection of any virus.

Initial materials for this type of replacement blood include chemicals used to create atomic bombs, bull blood, and nourished blood in bacteria.

However, until now, scientists around the world have failed to create a safe alternative blood type.

According to Professor Chris Cooper, a biologist and blood replacement specialist at Essex University, the reason for this failure lies in hemoglobin, the hemoglobin in the blood cells that transport oxygen throughout the body. . When removed from the protective environment of red blood cells, hemoglobin can be poisoned.

Normally, hemoglobin changes color from red to red wine when it transfers oxygen throughout the body. However, when it is destroyed, the iron ions in hemoglobin will oxidize, producing unusual blue and brown products.

'Basically, hemoglobin produces free radicals that can harm the heart and kidneys,' Professor Cooper explained.

'The challenge for artificial blood is that it must change the hemoglobin molecules so that they become less toxic, but still have to maintain their vital role in transporting oxygen throughout the body. But no one has been able to handle this problem. '

What makes GS Cooper's research group so special is because the hemoglobin they produce is less toxic.

In Daybreakers, a race of time to produce an alternative artificial blood can protect humans and vampires from extinction.

In the world of science, the need to create an artificial blood substitute is not so urgent, but a race is a good thing and really is going on.
