From bacteria to humans\, biological systems arise from a common set of atomically precise nanoscale building blocks s uch as proteins that give rise to complex functions such as sensing\, comp utation\, and actuation.\n\nIn contrast\, most human-made devices are comp osed of building blocks with much less precision\, and are assembled throu gh a top-down process which is highly inflexible and unsustainable. Drawba cks aside\, these devices are highly useful and can often surpass their bi ological counterparts (e.g.\, computers playing chess). This success is la rgely due to a systematic and modular engineering approach where simple bu t well-understood components such as transistors are put together in a pro grammable way. Is it possible to develop a new approach to building comple x devices that combines the strengths of biomolecular self-assembly and sy stematic engineering?\n\nIn this talk I will discuss recent work towards t his goal using DNA as a nanoscale\, programmable building block [1-5]. How ever\, despite being the most programmable molecule for information proces sing\, DNA lacks the basic physical attributes required for building high performance electronic devices.\n\nI will discuss ongoing work towards a n ew type of nanoscale building blocks in which DNA can be flexibly replaced with other materials such as metals and semiconductors. These nanoscale m odules can be designed to self-assemble into a variety of plasmonic\, phot onic\, and electronic architectures unattainable with any current nanofabr ication techniques. This novel approach integrates the advantages of natur al bottom-up assembly and engineered top-down programming and may lead to a host of new intelligent devices for technology and medicine. Two specifi c devices we are currently developing in our lab are single photon sensors with spectral resolution and electronic sensors for multiplexed detection of large biological targets.\n\nReferences:\n\n1.
