New method for making synthetic collagen

In a significant advance for cosmetic and reconstructive medicine, scientists at Rice University have unveiled a new method for making synthetic collagen. The new material, which forms from a liquid in as little as an hour, has many of the properties of natural collagen and may prove useful as a scaffold for regenerating new tissues and organs from stem cells.

Low-cost, portable technique can detect specific proteins in human blood

Blood tests are important diagnostic tools. They accurately tease-out vanishingly small concentrations of proteins and other molecules that help give a picture of overall health or signal the presence of specific diseases. Current testing procedures, however, are expensive and time-consuming, while sophisticated test equipment is bulky and difficult to transport.

New fertilized cells narrowly avoid degenerating into fatal chaos

Research based at Princeton University has revealed that newly fertilized cells only narrowly avoid degenerating into fatal chaos. At the same time, scientists have discovered that embryos have acquired a mechanism to contain this dangerous instability, a finding that could help biologists unravel other mysteries about the first hours of life.

Pittsburgh researchers combine Viscotek GPC and Zetasizer Nano in work on novel polymers for drug delivery

Molecular weight and molecular weight distribution measurements are a basic necessity in studying the synthesis of the novel polymers being carried out by researchers at the Department of Bioengineering at the University of Pittsburgh. For the Pittsburgh team, the applications and technical expertise provided by Malvern Panalytical is a significant factor in their use of the company’s Viscotek gel permeation chromatography (GPC) system to characterize polymer molecular weight, prior to applying the Zetasizer Nano for zeta potential measurements to study inter-molecular interactions.

Insect virus holds key to safer stem cell therapy: Singapore scientists

The future of regenerative medicine lies in harnessing the potential of the human body to renew and repair itself. Now, scientists at the Institute of Bioengineering and Nanotechnology (IBN), the world's first bioengineering and nanotechnology research institute, have developed a new genetic engineering technique that promises safer stem cell therapy for cancer patients. Using an insect virus, the team of researchers successfully inserted a therapeutic gene into a safe site in the DNA of human embryonic stem cells without compromising the functionality of the engineered cells.
