In the words of the CAMINEMS project coordinator, Dr Jean-louis Viovy of the Curie Institute in Paris, the key to the project was contained in the microfluidics techniques. icrofluidics is the equivalent for biology of microcircuits and microprocessors for the electronics industry

which allows specific biological elements to be switched in or out. The tool can thus be adapted according to whatever specific test the user wishes to conduct. ll the biology is contained in magnetic particles that we put in the system at the moment of operation.

and analyze them in sophisticated labs. Now a team of biologists has created a new tool that could provide a quick cheap way to perform sophisticated lab analyses

and diagnostics in the field and may also offer a way to speed science in the lab. The tool called a paper gene circuit takes biological reactions out of cells and puts them onto a piece of paper.

Over the past 15 years biologists have created hundreds of these gene circuits picking and choosing useful bits of biology

In contrast biological signals are less clear: in addition to"signal"and"no signal"there is a plethora of intermediate states with"a little bit of signal".

A team led by ETH Zurich Professor Yaakov Benenson has developed several new components for biological circuits.

The researchers recently published their work in the scientific journal Nature Chemical Biology. To understand the underlying technology it is important to know that these biological sensors consist of synthetic genes that are read by enzymes

and converted into RNA and proteins. In the controllable biosensor developed by doctoral candidate Nicolas Lapique the gene responsible for the output signal is not active in its basic state as it is installed in the wrong orientation in the circuit DNA.

In biology there are a variety of different signals a host of different proteins or microrna molecules.

In order to combine biologic components in any desired sequence signal converters must be connected between them. Laura Prochazka also a doctoral candidate student under Benenson has developed a versatile signal converter.

This new biological platform will significantly increase the number of applications for biological circuits.""The ability to combine biological components at will in a modular plug-and-play fashion means that we now approach the stage

when the concept of programming as we know it from software engineering can be applied to biological computers.
