A new 3D printed vaccine patch that outperforms needle jab to boost immunity

Scientists at Stanford University and the University of North Carolina at Chapel Hill have created a 3D-printed vaccine patch that provides greater protection than a typical vaccine shot. The trick is applying the vaccine patch directly to the skin, which is full of immune cells that vaccines target. The resulting immune response from the vaccine patch was 10 times Read more about A new 3D printed vaccine patch that outperforms needle jab to boost immunity[…]

4D printing will allow minimally invasive, pain-free and easy-to-use microneedles for delivering drugs

Painful hypodermic needles may not be needed in the future to give shots, inject drugs and get blood samples. With 4D printing, Rutgers engineers have created tiny needles that mimic parasites that attach to tissues and could replace hypodermic needles, according to a study in the journal Advanced Functional Materials. While 3D printing builds objects layer by Read more about 4D printing will allow minimally invasive, pain-free and easy-to-use microneedles for delivering drugs[…]
