[ China Pharmaceutical Network Technology News ] Scientists have built and tested a walking robot. In the future, similar nano-robots may be used to assemble new chemicals and materials at the molecular level, or to build ultra-small electronic circuits. It can be used to deliver drugs in blood vessels.
The walking robot built and tested by scientists is capable of capturing and carrying tiny objects that are too small to be seen by the naked eye. This robot is built from DNA, and the DNA molecule is responsible for carrying the genetic instructions of all living organisms.
According to Lulu Qian, a scientist at the California Institute of Technology, “just as electromechanical robots are sent to distant places like Mars, we want these molecular robots to enter tiny places that humans cannot reach, such as blood vessels. Our goal is to design and build A molecular robot capable of performing complex nanoscale tasks."
This nano-robot uses three basic building blocks to provide the "foot" for walking, the "arm" and "hand" for picking up objects, and it also recognizes specific release points and releases "goods." Each part of it consists of several nucleotides.
In the test, the nano-robot performed a task of exploring the molecular surface. The robot took two different fluorescent dye molecules and transported them to specific target locations. The researchers say that in principle the DNA robot can be designed to have many arms and hands so they can carry several molecules at a time.
Dr. Qian added: “We will not develop any special-purpose DNA molecules. Our laboratory is dedicated to exploring the engineering principles for developing universal DNA robots. However, I also hope that other researchers can use these principles to explore other exciting ones. Applications, such as the use of DNA robots to synthesize therapeutic chemicals in an artificial molecular plant, or to deliver drugs when blood flow and cells give specific signals, or to organize the molecular makeup in the body for recycling."

Toilet Chair
Toilet Chair, with closestool similar, can cent is double use type, sponge type, cover type, sofa type wait for type, suit the old person with weak body or action inconvenient patient,which is Safe Commode Chair, do life auxiliary use. Toilet tools are common items in the home and in hospital. In the hospital, family, there are always those old people with inconvenient legs, or patients, the toilet is always very inconvenient at night, in the case of no one to care at night, the elderly want to go to the toilet by themselves is very difficult. Toilet tools are common items in the home and in hospital. Considering the actual needs of the special population, the reform of toilet tools has become a concern.This is Household Toilet Chair
