From wikipedia:
>DNA computing is fundamentally similar to parallel computing in that it takes advantage of the many different molecules of DNA to try many different possibilities at once.[11] For certain specialized problems, DNA computers are faster and smaller than any other computer built so far. Furthermore, particular mathematical computations have been demonstrated to work on a DNA computer. As an example, DNA molecules have been utilized to tackle the assignment problem.[12] Aran Nayebi[13] has provided a general implementation of Strassen's matrix multiplication algorithm on a DNA computer, although there are problems with scaling. In addition, Caltech researchers have created a circuit made from 130 unique DNA strands, which is able to calculate the square root of numbers up to 15.
Perhaps it can be used in nanobots. Also being slow isn't necessarily a disadvantage if it could be made much cheaper. Biology can rapidly self-replicate out of everyday materials. It can also run efficiently on chemical energy and even sunlight. Though these likely don't apply to this research, just biocomputers in general.

In order to make (nano) artifical biological parts, you have to use really expensive chemical building blocks, or, if it's biologically (and not petrochemically) derived go through expensive finishing steps. > Biology can rapidly self-replicate out of everyday materials. Then you're adding at least a micron of space overhead. > It can also run efficiently on chemical energy and even sunlight Also true of mechanical parts, for example palladium nanoparticles running off of peroxide, or light-driven silver nanoparticles. running off of sunlight is a nontrivial process for biology (turns out oxygen wrecks a lot of really important enzymes), and biology is actually not very good at it.
