3D-Printed DNA “Glue” Could Lead to Bio-Engineered Tissues/Organs


In an article entitled “3D Printing with Nucleic Acid Adhesives” published in ACS Biomaterials Science & Engineering, researchers have successfully  demonstrated an inexpensive process that according to the ACS article creates ” DNA-coated nanoparticles made of either polystyrene or polyacrylamide. DNA binding adhered these inexpensive nanoparticles to each other, forming gel-like materials that they could extrude from a 3-D printer. The materials were easy to see and could be manipulated without a microscope. The DNA adhesive also allowed the researchers to control how these gels came together. They showed that human cells could grow in the gels, which is the first step toward the ultimate goal of using the materials as scaffolds for growing tissues.”  Read more at: http://www.acs.org/content/acs/en/pressroom/presspacs/2015/acs-presspac-january-14-2015/dna-smart-glue-could-someday-be-used-to-build-tissues-organs.html or the full article:

VBLOC – FDA Approved Implant for Reducing Obesity

VBLOC - sp_image_role_of_vagus_nerve

Currently, in the United States nearly 77 percent of females and more than 80 percent of males aged 15 and older are estimated to be overweight or obese (BMI ≥ 25 kg/m²), according to the World Health Organization.

VBLOC by EnteroMedics is an implanted therapy that supports patients who need to lose weight by helping them feel less hungry, reduce the amount of food eaten at a meal, and feel full longer in between meals.This new therapy helps regulate the vagus nerve, which is responsible for Sensations of hunger, satisfaction and fullness.

Painless Tattoo-Sensor to Detect Glucose Levels

Scientists in the Department of NanoEngineering at the University of California, San Diego have developed a proof-of-concept for a Tattoo-Based Noninvasive Glucose Monitor. This is a very thin, flexible, wearable device that sticks to skin like a rub-on tattoo and can detect a person’s glucose levels in the fluid just under the skin. The sensor, reported in a proof-of-concept study in the ACS journal Analytical Chemistry, has the potential to eliminate finger-pricking for many people with diabetes.

3D-printed Exoskeleton Enables Woman to Walk Again


More amazing work in the field of 3D-printing. From an article on gizmag.com:

“3D Systems, in collaboration with Ekso Bionics, has created a 3D-printed robotic exoskeleton that has restored the ability to walk in a woman paralyzed from the waist down. The Ekso-Suit was trialled and demonstrated by Amanda Boxtel, who was told by her doctor that she’d never walk again after a skiing accident in 1992.” Read and see more at: http://www.gizmag.com/3d-printed-robotic-exoskeleton/30893/


Apple ResearchKit – Framework to Help Medical Research

Apple ResearchKit

Apple has released an open-source framework to allow researchers to develop applications that leverage the iPhone’s sensors for tracking movement, taking measurements, and recording information. Using ResearchKit, this information can now be available for use in medical studies, supporting the research and development efforts in the field of medicine.

OnKöl – The Elderly to Family Connector

onkol - stay-connected

Today we have a soon-to-be-available product targeted at the elderly and their family/caregivers. From the company website:

“OnKöl is a simple-to-use invention that connects elderly and those with special needs to their family and caregivers. It provides a team approach to helping care for a loved one, while allowing them to continue to live independently in their home.

OnKöl simultaneously notifies selected family members and other caregivers of everything from vital signs to incoming and outgoing calls to emergency or panic situations. That way, the caregivers and interested parties can get out in front of specific events or anomalies, before they become full-blown emergencies.”
