Living Bioink for 3D-Printed Living Devices
A group of researchers from the Massachusetts Institute of Technology (MIT) generate living materials and devices by 3D printing genetically programmed bacterial cells. The living bioink can be used to print novel materials including logic gates and a living tattoo for chemical detection on human skin.
Immunity to CRISPR Cas9 and Cas12a Therapeutics
Genome-editing therapeutics introduce foreign nucleic acids and proteins into the circulation and cells, which can activate the innate, cellular, and humoral immunity in human patients. The key obstacle in translating CRISPR therapeutics to the clinic is hence to identify, diminish, and monitor these immunological risks before adverse immune reactions.
Breaking free from vascular confinement: status and prospects for submicron ultrasound contrast agents
In contrast to healthy tissue, tumors demand a high supply of nutrients and oxygen, and will invade existing vessels and develop new ones to meet these demands.
Safe Smiling: Bleaching Teeth Using Plasma Jet
Taiwanese scientists create a new atmospheric-pressure plasma jet tooth bleaching method that is safe, cost effective and portable.
Reinventing Wood
Wood could potentially replace petrol in chemistry and concrete in construction, according to studies conducted under the Swiss Research Programme “Resource Wood”.
Polymer Microcups for Neural Devices and Drug Delivery
University of Houston and Pennsylvania State University researchers fabricate conducting polymer microcups from polylactic-co-glycolic acid (PLGA) for neural applications and drug delivery. These microcups are tunable in terms of size, surface roughness, electrical properties, and drug release.
Lemon-based Bio-Plastics
Spanish researcher found a way to replace bisphenol-A with limonene in polycarbonates.
Fiber Directed Cell Growth in Injectable Hydrogels
A simple and effective, injectable hydrogel system with tunable fiber orientation for directed cell growth in demonstrated.
