In a carefully designed polymer, researchers have imprinted a sequence of a single strand of DNA. The resulting negative remained chemically active and was capable of binding the appropriate nucleobases forming a genetic code. The polymer matrix thus functioned exactly like a sequence of real DNA.
Scientists have designed a new screen, which is cheaper and ecological as it uses a hybrid material. This material's luminescent proteins can be used in backlighting systems and colour filters made using a 3D printing technique.
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.
The approach consists of two cascaded microring resonators, with one serving as the sensing device and the other playing the role of a reference - thus eliminating environmental and system fluctuations such as temperature and laser frequency.
In a new study, researchers investigate why hair is incredibly strong and resistant to breaking. The findings could lead to the development of new materials for body armor and help cosmetic manufacturers create better hair care products.
In research that could one day lead to advances against neurodegenerative diseases like Alzheimer's and Parkinson's, engineering researchers have demonstrated a technique for precisely measuring the properties of individual protein molecules floating in a liquid.
Microbiologists report that they have discovered a new type of natural nanowire produced by bacteria that could greatly accelerate the researchers' goal of developing sustainable 'green' conducting materials for the electronics industry.
