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.
