The breakthrough technology of the world medicine in the past time

From artificial hearts to 3D printed corneas, science and technology are creating powerful unprecedented breakthroughs in the medical field, when making things that can't be possible!

3D printed cornea

With 3D printing technology, they produce a nearly identical bridge to the human cornea.

The cornea is the outermost transparent layer of the eye usually about 11mm in diameter. The cornea plays a role in protecting sensitive parts of the eye from dirt and bacteria, and acts as a lens to control and focus light rays into the eyes, thereby helping us see clearly at different distances.

When the cornea is damaged by a physical impact or some ophthalmic diseases, human vision may be severely impaired or completely lost. In the face of the huge demand for corneal transplants every year while the number of donated corneas is quite small, researchers at NewCastle University have found a way to create artificial senses thanks to printing technology. 3D.

Accordingly, the scientists blended stem cells, extracted from healthy corneas, Alginate and Collagen, to create a printable mixture called 'Bio-Ink'. . Then, with 3D printing technology, they produced a close match to the human cornea. Currently this research group is taking the next steps to test this type of 3D printed cornea on humans, in the near future!

Cure cancer with water

This is also the only magnetic liquid in normal conditions.

An invention of less than half a decade is receiving special attention from scientists because they believe that this product is the key to the goal of healing cancer.

The invention mentioned is a special liquid named FerroFluid (also known as magnetic water) . This is also the only magnetic liquid in normal conditions, it was invented by NASA in 1960 to control the flow of liquid fuel in a zero gravity environment. With this special physical property, scientists hope that water can be used to transport drugs, in a way that is oriented, to cancer cells and to resistant bacteria.

In addition, the size of the water is small enough to penetrate into the cancer cell. At this point, a magnetic field will be applied so that the water from heating up and destroying cancer cells, without affecting healthy cells!

3D printed hearts

The artificial heart is only about the size of a rabbit's heart, but it can be operated smoothly.

On April 15, researchers at Tel Aviv University, Israel, successfully created a complete artificial heart, full of organs (vascular, ventricular, and heart cells). atrium .) as a normal heart.

According to the team's representative, in order to create this artificial heart, they extracted the patient's fat cells to "decompose" it into stem cells, then use the same stem cells to differentiate into Heart and endothelial cells, this is also the key ingredient for creating 'biological ink ' for 3D printers to create artificial hearts.

The artificial heart is only about the size of a rabbit's heart, but it can be operated smoothly. With this breakthrough, the team hopes that, in the next decade, not only the heart but also other organs can be created by 3D printing, at each hospital to serve patients promptly. need an organ transplant!
