Exponential assembly at Zyvex

from the manufacturing-architectures dept.
Some Fat Guy writes "There is an interesting paper and Real Video animations on Exponential Assembly here: http://www.zyvex.com/Research/exponential.html The devices described are MEMS devices, but the concept scales down." CP: A more formal journal article from the Foresight Conference is linked to at the end.

Smart Dust-Spies in the Sky from UC Berkeley

from the he-knows-if-you've-been-bad-or-good dept.
EddieWehri brings our attention to an article in the San Francisco Chronicle: "Yep, yet one more SF concept from books like The Diamond Age make it into prime time. MEMS science is producing dust sized surveillence devices that are lighter than air and float around collecting data and reporting back to the mother base." Excerpt: "Each mote contains a solar cell to generate power, sensors that can be programmed to look for specific information, a tiny computer that can store the information and sort out which data is worth reporting, and a communicator that enables the mote to be 'interrogated' by the base unit…'This is a technology of total surveillance' "

MEMS news site based on Slash software

from the MEMSdot dept.
For the MEMS (MicroElectroMechanical Systems) fans among us, Jonathan Desp brings to our attention MEMS Center, a new MEMS portal based, as is Nanodot, on the Slash news-and-discussion software. Read More for his full post.

Confocal microprobe planned to view living cells

from the now-open-wide dept.
Mark Baltzegar brings our attention to plans for a confocal imaging "scanning microprobe" using MEMS technology which would enable imaging of living cells deep within the human body. "Currently we have no way to effectively study the real living behavior of cells in detail because we lack the advanced visualization tools to see them in their natural environment," commented Dr. John Liddicoat, Cardiac Surgeon at Allegheny General Hospital in Pittsburgh, PA. "The opportunities for real-time visualization down at the cell level would be incredibly valuable. We could realize a broad range of uses in medicine. For example, by applying this technology, we may be able to accurately direct pharmacological and mechanical interventions in such diverse fields as cardiology, pulmonolgy, oncology, and transplantation, just to name a few. This type of visualization tool would be enormously valuable."

BioMEMs moves toward nanometer scale

from the top-down-bottom-up-whatever-works dept.
Senior Associate Brian Wang brings to our attention a press release from the University of Illinois at Chicago on work presented at the BioMEMs & Biomedical Nanotechnology World 2000 conference: "Another example of therapeutic BioMEMs that Desai will discuss are cell encapsulation devices with nanometer-sized pores that can protect implanted cells or components from large molecules like antibodies while allowing small molecules like hormones and nutrients to freely pass through. Such devices, which have long been dreamed of for implanting pancreatic islet cells in diabetic patients or neurosecretory cells in Parkinson's or Alzheimer's patients, are now being fabricated in Desai's laboratory by micro-machining silicon to create precisely controlled micro- and nano-architectures."


from the really-tiny-scrubbing-bubbles dept.
GinaMiller (and others) wrote "Simulation shows that liquid jets a few nanometers in diameter might have the potential to produce ever-smaller electronic circuitry, inject genes into cells, or etch tiny features. Writing in the August 18 issue of Science, Georgia Tech researchers suggest that jets as small as six nanometers in diameter may be possible — though they will require special conditions to operate and be sensitive to effects not of concern to macroscopic jets. As a next step, the researchers would like to create nanojets experimentally and use them to apply patterns that could replace current lithographic processes in the manufacture of nanoscale miniaturized circuits. They could potentially also be used as "gene guns" to insert genetic materials into cells without causing damage. The researchers produced some nice graphics "

Open Source CAD code for MEMS

from the where-oh-where-is-good-software dept.
Senior Associate Michael Butler writes "At the just-past Foresight Gathering, mention was made of extant MEMS fab CAD software packages and how bad they are. Alternatives mentioned include, e.g., recycling mature finite element FORTRAN code and stitching it together with other things. It happens that Matra open sourced a bunch of CAD/CAM code last year. (Slashdot article). I suggest that interested people at Zyvex and elsewhere check out Open Cascade and see if what they're doing can be bent to your purposes. Have any nanodotters worked with this code?
