Gels for drug delivery systems

'Soft' 3D printing could jump-start creation of tiny medical devices

Researchers at the U.S. National Institute of Standards and Technology (NIST) have developed a new method of 3D-printing gels and other soft materials. Published in a new paper, it has the potential to create complex structures with nanometer-scale precision.

The science behind 3-D printed nasal swabs

Medical device approved 3-D printers are producing clinically safe and effective nasopharyngeal swabs for COVID-19 testing. A nasal swab may seem rudimentary, but is essential for testing COVID-19. Diagnostic test kits and components – nasal swabs, collection vials, and chemical reagents – have been in short supply worldwide, especially in March. Ironically, nasopharyngeal swabs are…

Improving first aid

New 3D CT scanning method shows what happens during CPR

Rapid first aid during cardiac arrest makes the difference between life and death. But what happens to the heart and the internal organs when people come running and begin to give well-meaning but heavy-handed heart massage as they attempt to keep the person who has suffered a cardiac arrest alive? A research collaboration between the Department of Forensic Medicine at Aarhus University and the…

3D microprinted scope

World’s smallest imaging device focuses on heart disease

A team of researchers led by the University of Adelaide and University of Stuttgart has used 3D micro-printing to develop the world’s smallest, flexible scope for looking inside blood vessels. The camera-like imaging device can be inserted into blood vessels to provide high quality 3D images to help scientists better understand the causes of heart attack and heart disease progression, and could…

Diabetic damage

3D imaging shows how diabetes twists nerve fibers

In an international collaboration led by Lund University in Sweden, researchers have used synchrotron light to study what happens to the nerves in diabetes. The technique shows the 3D-structure of nerve fibers in very high resolution. “This knowledge can be used to map mechanisms for how nerve fibers atrophy and grow back. It means that we can better understand how diabetes affects the nerves…

3D printing sensors for diabetes breath tests

The production of highly sensitive sensors is a complex process: it requires many different steps and the almost dust-free environment of special cleanrooms. A research team from Materials Science at Kiel University (CAU) and from Biomedical Engineering at the Technical University of Moldova has now developed a procedure to produce extremely sensitive and energy-efficient sensors using 3D…

Glioblastoma

New imaging technique to study 3D printed brain tumors

Glioblastomas are complex, fast-growing malignant brain tumors that are made up of various types of cells. Even with aggressive treatment — which often includes surgery, radiation, and chemotherapy — glioblastomas are difficult to treat, leading to an average survival of 11-15 months. In research published in Science Advances, Xavier Intes, a professor of biomedical engineering at Rensselaer,…

3D radiography extension

FDA clearance for Digital Tomosynthesis

Carestream’s Digital Tomosynthesis (DT) functionality—a three-dimensional extension of general radiography—has received 510(k) clearance from the U.S. Food and Drug Administration (FDA). Simplifying workflow and reducing exam time, DT technology is an upgradable option on the Carestream DRX-Evolution Plus System, a versatile digital radiography system that can perform a wide range of…

Non-alcoholic fatty liver disease

3D model of human liver tissue for better NAFLD diagnosis

Non-alcoholic fatty liver disease (NAFLD) is becoming the most common chronic liver disorder in developed countries. Histological analysis of liver tissue is the only widely accepted test for diagnosing and distinguishing different stages of NAFLD. However, this technique provides only two-dimensional images of the liver tissue in low resolution and overlooks potentially important 3D structural…

Endoscopy solution

It’s time for colonoscopy and gastroscopy in 3D

Minimally-invasive surgery (MIS) benefits from 3D visualization with improved image quality and depth perception. Now, a 3D solution for gastroscopy and colonoscopy is available, by simply connecting a device to the hospital’s existing flexible endoscopy equipment with a 3D monitor. This solution is presented by MedicalTek (MDTK), a Taiwanese company specialized in the field of medical image…

Hope for new skin grafts

3D printed living skin complete with blood vessels

Researchers at Rensselaer Polytechnic Institute have developed a way to 3D print living skin, complete with blood vessels. The advancement, published in Tissue Engineering Part A, is a significant step toward creating grafts that are more like the skin our bodies produce naturally. “Right now, whatever is available as a clinical product is more like a fancy Band-Aid,” said Pankaj Karande, an…

Tissue construct

A 'swift' way to 3D-print organs

Twenty people die every day waiting for an organ transplant in the U.S., and while more than 30,000 patients now receive transplants annually, another 113,000 are currently on organ waitlists. Many people see artificially grown human organs as the Holy Grail for resolving the organ shortage, and advances in 3D printing have led to a boom in using that technique to build living tissue constructs…

Producing tissue and organs through lithography

The production of artificial organs is a hot research topic. In the near future, artificial organs will compensate for the lack of organ donations and replace animal experiments. Although there are already promising experiments with 3D printers that use a „bio-ink“ containing living cells, a functional organ has never been created in this way. A European consortium coordinated by Dr Elena…
