Brainstorm Ideas


Impulse Signal

  • one suggestion (by Federico C.) from the idea exchange was to create a self-destructing plasmid, which would express once and than destroy itself with a restriction endonuclease in its code.


Water Soluble Vitamin Production

  • produce Vitamins B and C.


Stop Quorum Signalling -> Quenching AHL

  • aiiA enzyme [http://www.msk.or.kr/jsp/view_old_journalD.jsp?paperSeq=2133] already has a biobrick [http://partsregistry.org/Part:BBa_C0060 Part:BBa_C0060] but it is not secreted.
  • halogenated furanones [http://mic.sgmjournals.org/cgi/content/full/151/11/3589?view=long&pmid=16272381] [http://mic.sgmjournals.org/cgi/content/full/148/4/1119?view=long&pmid=11932456] decrease binding activity of LuxR.
  • [http://www.molbio.princeton.edu/index.php?option=content&task=view&id=27 Bonnie Bassler]'s research, inhibit quorum signaling with molecules structurally similar to AHL. Her recent [http://www.ted.com/index.php/talks/bonnie_bassler_on_how_bacteria_communicate.html TED Talk].


Biological Isotope Separation

  • is it even possible?
  • according to this [http://jol.liljenzin.se/BOOK.HTM book] in section 2.6.5. [http://jol.liljenzin.se/KAPITEL/CH02NY3.PDF], both chlorella algae and E.coli have isotope enrichment properties (hydrogen, deuterium). no references given.
  • possible applications: remove radioactive isotopes from body (cancer treatments), separate heavy water from ocean water, remove carbon 14 and potassium 40 from body/food.
  • another paper is Bioseparation of Lithium Isotopes by Using Microorganisms, Sakaguchi, Takashi | Tomita, Osamu, Resource and Environmental Biotechnology [Resour. Environ. Biotechnol.]. Vol. 3, no. 2-3, pp. 173-182. 2000. havent found a copy online.


Saltwater Purification

  • + heavy metal extraction
  • diatoms
  • Dead Sea organisms
  • [http://www3.interscience.wiley.com/journal/117915599/abstract?CRETRY=1&SRETRY=0; Lyotropic liquid crystals] - Lyotropic liquid crystal (LLC) structures can be used as selective membranes to seperate between certain chemicals (e.g. removing salt molecules from water molecules). If it is possible, we could design a bacteria that would have the LLC as a membrane, culture this bacteria and put it in saltwater, so that it removes the salt from the water, and then remove the bacteria altogether. Question is, can LLC be used as a bacterial membrane?

Xylitol production

  • already attempted, see [http://openwetware.org/images/0/03/6-bolaji.pdf]


Melatonin Compensation

  • compensate the reduction in melatonin levels caused by the invention of electrical lights
  • has been linked to lots of medical problems, see review paper [http://www.psy.ohio-state.edu/nelson/documents/JPinealRes2007.pdf The dark side of light at night: physiological, epidemiological, and ecological consequences]
  • would need to implement melatonin detection, synthesis, and a clock


New Antibiotic Cassettes

  • Biobricks exist for Ampicillin, Kanamycin, Chloramphenicol, and Tetracycline.
  • New biobricks needed (see TK:Wishlist), integrate into larger project?
  • Cationic peptides, Rhodostreptomycins [http://mit.edu/biology/sinskey/www/Kurosawa2008.pdf]


Paper Based Microfluidics with bacteria

  • Improve the processing outlined in [http://www.rsc.org/delivery/_ArticleLinking/ArticleLinking.cfm?JournalCode=LC&Year=2008&ManuscriptID=b811135a&Iss=12 FLASH: A rapid method for prototyping paper-based microfluidic devices], see papers from Whitesides group at Harvard.
  • use light sensor and output hydrophobic/hydrophilic chemicals that can coat the cellulose in the paper placed on an agar plate


Close proximity phage expression

  • once a cell is close enough to a target, produce phages and explode
