Researchers have developed a 3D printing process that allows for a combination of both liquid and solid material in the finished process. Pictured shows the inside of the 3D-printed material (right), with a lattice structure (left) containing the added liquids.
However, for 3D printing to evolve, it must integrate more complex methods that combine several production steps. That is why we were looking for a way to integrate liquids directly into the material during the printing process,” Binder said in a press statement.
To achieve this goal, Binder, working with colleague Professor Harald Rupp married common 3D printing processes with traditional printing methods, such as those used in inkjet or laser printers. The new method adds liquids drop by drop in a specified location during the extrusion of the basic material, which allows them to be “printed” directly into the product as it’s forming, they said.
Researchers produce special nanoparticles and reveal their inner structure for the first time
New single-chain nanoparticles could be used in medicine or as nanoreactors in which chemical reactions take place
Tiny nanoparticles can be furnished with dyes and could be used for new imaging techniques, as chemists and physicists at Martin Luther University Halle-Wittenberg (MLU) show in a recent study. The researchers have also been the first to fully determine the particles internal structure. Their results were published in the renowned journal Angewandte Chemie .
Single-chain nanoparticles (SCNPs) are an attractive material for chemical and biomedical applications. They are created from just a single chain of molecules that folds into a particle whose circumference measures three to five nanometres. Because they are so small, they can travel everywhere in the human body and be used for a wide variety of purposes, says Professor Wolfgang Binder from the Institute of Chemistry a
