DNA 11: Personal DNA Portrait.
Un retrato de tu ADN para adornar tu casa, qué buena idea :D
The Watson Table, named after James Watson and designed by Paul Loebach. This otherwise minimalist design has spiraling legs that are inspired by DNA structure.
¿Mesa con las patas inspiradas en la estructura del ADN? ¡Me la pido!

DNA Nanorobot programmed to seek and destroy cells.
Researchers at Harvard University’s Wyss Insitute have created a barrel shaped structure out of DNA, which is capable of carrying a payload through the body and opening to release it when it finds certain types of cells.
Using the DNA origami method, in which complex three-dimensional shapes and objects are constructed by folding strands of DNA, the barrel is held shut by special DNA latches that can recognize and seek out combinations of cell-surface proteins, including disease markers. When the latches find their targets, they reconfigure, causing the two halves of the barrel to swing open and expose its contents, or payload. The container can hold various types of payloads, including specific molecules with encoded instructions that can interact with specific cell surface signaling receptors.
The work is a described as a “major breakthrough in the field of nanobiotechnology”, as it will be able to “meet a real-world challenge, namely killing cancer cells with high specificity”. By using biocompatible DNA nanotechnology, the system will be able to naturally dissolve in the body, lessening the side effects compared to traditional drugs. Because it is able to target specific cells, far smaller doses of drugs will be able to be given, while still increasing their effectiveness.
Muy buen avance en biotecnología, sí señor.
NUEVO BIOSENSOR DE NANOTUBOS DE CARBONO Y ADN
Investigadores de la Universidad de Purdue han desarrollado un método para apilar ADN sintético y nanotubos de carbono sobre un electrodo biosensor. Este sistema permitirá realizar mediciones mas precisas en investigaciones que tienen relación con la diabetes y otras enfermedades, ya que los actuales sensores no facilitan mediciones exactas.
Los nanotubos de carbono tienen una excelente cualidad térmica y eléctrica, por lo que se prevé que puedan mejorar dichos sensores. No obstante, hay un problema debido a su incompatibilidad con el agua, por lo que representa un problema al aplicarlo en fluidos biológicos.
