Effective biological ink for 3D printing of drugs developed by the researchers of the University of California at Los Angeles. His discovery, scientists have presented a 3D Medical Expo in Maastricht.
The lack of modern pharmacology is that it does not take into account the genetic specificity of the individual patient or of the blood. And because the genome of each person is unique, the body’s response to medication will be different.
Biochemie presented by scientists Los Angeles, created from hyaluronic acid — a key ingredient that is part of the skin, connective tissues and nervous system. Acid said property photoinitiator to harden on light, and mixed with hydrochloride ropinirole stimulating substances commonly used for relieving symptoms of Parkinson’s disease. Ropinirol was chosen to ensure that the drug is dissolved in the water.
Forming from the resulting biochannel pills, the scientists tested them in the acidic substances that mimic the gastric environment. In the first 15 minutes dissolved 60% of the total tablet. After another 15 minutes another 20%. The maximum effects of the drug achieved an hour after “reception”. The losses were insignificant, about 4%.
Method of printing Bikernieki was chosen by scientists because it has the advantage over other 3D technologies because of its speed and undemanding: drugs can be produced on an industrial scale and at room temperature.
Light sensitive inks are suitable for use in a 3D printer PolyJet, patent for which is owned by the company Stratasys. Simplifying technology to create expendable materials for bioprinting, scientists contribute to the same results for bioprinting to become effective, and the most common method of production of drugs, writes InternetMedicine.
A new kind of biochannel has been developed by scientists at the University of Bristol. It consists of organicheskih and synthetic polymers and allows to print on a 3D printer living tissue suitable for implantation as bone and cartilage.
