Long-Lasting Hydrogel Derived from Sea Anemones

  A team of researchers from Pohang and Yeungnam Universities have created a mechanically durable hydrogel inspired in a sturdy protein found in anemones that allows their contraction and relaxation movements. The silk-like protein, derived from anemone’s tentacles, allowed to produce the aneroin hydrogel, which proved to be a good support and environment for cells. […]

3D printing of embryonic stem cells in building blocks

  A new 3D printing method allows to obtain regular blocks of embyonic stem cells (ESCs) that could be used to build larger structures like tissues or organs. The researchers from Tsinghua University in Beijing and Drexel University in Philadelphia obtained uniform and homogeneous embryoid body structures that can facilitate further tissue growth. The study was published in the […]

New 3D Bioprinting Method Obtains Heart Model

Researchers from Carnegie Mellon University have printed 3D models of hearts, bones, arteries and brains using soft biological materials. The models were based on 3D high-resolution images of real organs. The new technique solves the problems in using gels for bioprinting. The study has been published in the journal Science Advances. 3D printing has progressed […]

3D Bioprinting Directed by DNA “Stickers”

Scientists from UCSF have developed a new 3D bioprinting technique – DNA Programmed Assembly of Cells (DPAC) – were cells are joint together by DNA strands hanging in the outer part of the lipid bilayer. The complementarity of DNA strands allows cells to be placed like building blocks and grown in a specific fashion to develop tissues and organoids. The […]

3D Printed Microfish Used for Detoxification

Functionalizing the microfish. Platinum nanoparticles are loaded into the tail for propulsion via reaction with hydrogen peroxide. Next, iron oxide nanoparticles are loaded into the head for magnetic control. Image credit: W. Zhu and J. Li, UC San Diego Jacobs School of Engineering.Nanoengineers from the University of California, San Diego have developed fish-shaped microrobots that swim in […]

3D Printing of Brain-like Tissues to Improve Drug Tests

Scientists from the ARC Centre of Excellence for Electromaterials Science (ACES) have developed a multi-layered structure of primary neural cells that imitates the brain structure. The finding, published in the journal Biomaterials, will improve the brain drug screening process by providing a better material to work in vitro than the ones currently used. The brain is […]
