next time I hear that, I'm going to say, "Cells are the future!" They won't have a clue, but someday, it'll make sense to everyone. And I'm thinking that 'someday' isn't too far off.

Very interesting - BUT - I thought circuit boards were being "grown" from bio-stuff like bacteria for decades already. ...???

MLO (Multi-Layer Organic packaging) combines advanced RF circuit materials based on liquid crystalline poly- mers (LCP) and ceramic-filled polytetrafluorethylene (PTFE) composites, coupled with novel processing and circuit topologies.

Conclusion
A reliable, high-performance organic package with embedded passive components has long been sought by the semiconductor industry. MLO has shown that such a goal is obtainable, and that organic packages are capable of challenging conventional multi-layer ceramic technology for the next generation of wireless SiP products.

Bugging me big time, but Gord went blind and moved away so can't ask him. Had to google. Found only this:

Biocomputers can be an alternative for traditional "silicon-based" computers, which continuous development may be limited due to further miniaturization (imposed by the Heisenberg Uncertainty Principle) and increasing the amount of information between the central processing unit and the main memory (von Neuman bottleneck). The idea of DNA computing came true for the first time in 1994, when Adleman solved the Hamiltonian Path Problem using short DNA oligomers and DNA ligase. In the early 2000s a series of biocomputer models was presented with a seminal work of Shapiro and his colleguas who presented molecular 2 state finite automaton, in which the restriction enzyme, FokI, constituted hardware and short DNA oligomers were software as well as input/output signals. DNA molecules provided also energy for this machine. DNA computing can be exploited in many applications, from study on the gene expression pattern to diagnosis and therapy of cancer. The idea of DNA computing is still in progress in research both in vitro and in vivo and at least promising results of these research allow to have a hope for a breakthrough in the computer science.

1990: Development of a biochemical switching device: mathematical model.

The author previously showed with computer simulations that cyclic enzyme systems have the reliability of ON-OFF types of operation (McCulloch-Pitts' neuronic equation) and the applicability for a switching circuit in a biocomputer. The switching time was inevitably determined in accordance with the difference in amount between two inputs of the system. A unique switching mechanism of cyclic enzyme systems (basic switching element) and the effects of excitatory stimuli on switching properties of the integrated biochemical switching system are demonstrated.

2000: Biological computing

The concept of biocomputing, its possible applications, and recent theoretical and experimental research relevant to biological computing are reviewed. In particular, attention is given to the creation of genetic flip-flops (one-bit switches), construction of genetic clocks, amorphous computing, current work concerned with the development of techniques for exchanging data between cells, and the first DNA-based biocomputer prototypes.

2008: Refinement and standardization of synthetic biological parts and devices

Abstract
The ability to quickly and reliably engineer many-component systems from libraries of standard interchangeable parts is one hallmark of modern technologies. Whether the apparent complexity of living systems will permit biological engineers to develop similar capabilities is a pressing research question. We propose to adapt existing frameworks for describing engineered devices to biological objects in order to (i) direct the refinement and use of biological 'parts' and 'devices', (ii) support research on enabling reliable composition of standard biological parts and (iii) facilitate the development of abstraction hierarchies that simplify biological engineering. We use the resulting framework to describe one engineered biological device, a genetically encoded cell-cell communication receiver named BBa_F2620. The description of the receiver is summarized via a 'datasheet' similar to those widely used in engineering. The process of refinement and characterization leading to the BBa_F2620 datasheet may serve as a starting template for producing many standardized genetically encoded objects.

2009: nano bio computing - synthesis of a nano bio computer using DNA and nanorobots

Abstract: 1) The paper is on interfacing nanotechnology with bio technology to result a nano bio computer. 2) This technology will be capable of replacing the present generation laptops. 3) DNA is used as a memory storage device instead of hard disks. Data’s are encoded and decoded in DNA strand by converting the text message to DNA language (a, c, g, t). 4) The invention of nano processor which is eco friendly too has helped our way to design this nano computer. 5) The processing unit consists of nano processors and nanorobots are made to carry the signals from one unit to another. MEMORY UNIT: DNA is used as a memory storage device. It can understand only the sequence of A, C, G, T and act accordingly. Thus, the data that has to be encoded are converted to a string of ACGT and embedded on the DNA strand and we can decode it whenever we want to retrieve the data. Conditions: DNA should be stable, no mutation should occur. Replication process should be halted. The shape and size of the DNA should be maintained. Data can be secured without any losses only when these conditions are achieved. PROCESSING UNIT: The arrival of nano processor to the market has made our job easier. The nano processors are programmed as per the requirement and it can be interfaced with other units through nanorobots. Nanorobots can carry signal from one unit to another. The output display is done using end projectors so that the user can project the output in wall. This makes the computers size will be as small as a pen.

...the most germy thing I've ever seen make it mainstream (to any degree) has been bacterial rhodopsin based stuff, like memory. Seems like there were some photosensors based on it too.

Bioelectronics is a recently coined term for a field of research that works to establish a synergy between electronics and biology.[1] One of the main forums for information about the field is the Elsevier journal Biosensors and Bioelectronics, published since 1990. The journal describes the scope of bioelectronics as follows:
The emerging field of Bioelectronics seeks to exploit biology in conjunction with electronics in a wider context encompassing, for example, biological fuel cells, bionics and biomaterials for information processing, information storage, electronic components and actuators. A key aspect is the interface between biological materials and micro- and nano-electronics.[2]

Applications of bionanotechnology are extremely widespread. Insofar as the distinction holds, nanobiotechnology is much more commonplace in that it simply provides more tools for the study of biology. Bionanotechnology, ...promises to recreate biological mechanisms and pathways in a form that is useful in other ways.

Bacterial quorum sensing: signals, circuits, and implications for biofilms and disease.

The focus of this review is on the principles underlying signal-mediated bacterial communication, with specific emphasis on the potential for using them in two applications-development of synthetic biology modules and circuits, and the control of biofilm formation and infection.

Evolutionary analysis indicates that the biofilm network has rapidly evolved: genes in the biofilm circuit are significantly weighted toward genes that arose relatively recently with ancient genes being underrepresented.
