Researchers develop new method to improve bioprinting resolution with Iodixanol
Researchers at the University of California San Diego have made advances in bioprinting 3D-engineered tissues. Bioprinting is a process of creating biological structures and tissues using cells and biopolymer. This study describes a type of bioprinting called digital light processing (DLP). Current bioprinting techniques have challenges in achieving key requirements of high cell density, high…

New technology to monitor chemotherapy using magnetic nanoparticles
Researchers from Michigan State University propose a novel non-invasive magnetic particle imaging (MPI) to monitor chemotherapy release in vivo. This method employs superparamagnetic nanoparticles as the contrast agent to monitor drug release in the body. In this study researchers designed iron oxide nanocomposite loaded with a chemotherapy drug doxorubicin which serves as a drug delivery…

Understanding interaction between heart muscle cells and nanoscaffoding
Researchers from Moscow Institute of Physics and Technology (MIPT) have researched nanofibrous scaffold structure and its interaction with rat heart muscle cells. This study revealed that cardiac muscle cells envelop nanofibers as they grow, but fibroblasts tend to spread out on fibers forming several focal adhesion sites. Nanofibers enveloped by Heart muscle cells. The 3-D…

Researchers create better wearable medical sensors based on graphene nano-flakes
Team of researchers at University of British Columbia Okanagan campus have developed a practical way to monitor and interpret human motion.The sensor is made by infusing graphene nano-flakes (GNF) into a rubber-like adhesive pad. Najjaran says they then tested the durability of the tiny sensor by stretching it to see if it can maintain accuracy…

New nanofiber bandages accelerate healing process
Researchers from National University of Science and Technology MSIS has presented a new therapeutic material based on nanofibers made of polycaprolactone modified with a thin-film antibacterial composition and plasma components of human blood. Biodegradable bandages made from these fibers will accelerate the growth of tissue cells twice as quickly, contributing to the normal regeneration of…

Gene therapy using lipid based nanoparticles
Lipid nanoparticles (SLNs and NLCs) are regarded as highly promising systems for delivering nucleic acids in gene therapy. Literature review by researchers at PharmaNanoGene describes these systems and their main advantages in gene therapy, such as their capacity to protect the gene material against degradation, to facilitate cell and nucleus internalization and to boost the transfection process. View…

Development of thin-film biomaterials using nanofibres to be used as scaffolding for bone regeneration
In future, it may be possible to use nanofibres to improve the attachment of bone implants, or the fibres may be used directly to scaffold bone regeneration. This would aid the healing of fractures and may enable the care of osteoporosis. This is detailed in a new dissertation. Hydroxyapatite nanofibre film produced at the University…

New approach to treating cancer with therapeutic short interfering RNA (siRNA) delivered by nanohydrogel nanoparticles
A novel targeted therapy using nanoparticles has enabled researchers at the Georgia Institute of Technology to purge ovarian tumors in limited, in vivo tests in mice. “The dramatic effect we see is the massive reduction or complete eradication of the tumor, when the ‘nanohydrogel’ treatment is given in combination with existing chemotherapy,” said chief researcher…
