==The Harvard University 2006 iGEM Team==
 +
This year Harvard's team consisted of 10 undergraduate students, with backgrounds in molecular and cellular biology, biochemistry, and computer science.  With the help of five faculty advisors and three graduate-level teaching advisors, they devised and executed three separate projects.
 +
1. Construction of novel DNA nanostructures for the purpose of stealth drug delivery,

2. Exploration of cell-surface targeting using interchangable and linkable aptamers (adaptamers) and Lpp-OmpA fusion vehicle for bacterial surface display.

The iGEM (intercollegiate Genetically Engineered Machine) Competition is a cutting-edge team research experience for students (undergraduate and graduate) interested in designing and building synthetic biological systems. This is an interdisciplinary challenge, so we are looking for students from all backgrounds of science and engineering who like to build cool things!
+
-
This year, ten undergraduates participated in three projects: reconstituting a circadian oscillator from cyanobacteria into E. coli, construction of novel DNA nanostructure drug-delivery devices, and exploring cell-surface targeting. More up to date information, including results, can be found on the wiki site which serves as a lab notebook: http://openwetware.org/wiki/IGEM:Harvard.

Harvard's 2005 Team was composed of 12 undergraduate students from biology to computer science, and freshman to seniors. And together they brainstormed, designed and partially implementing two cool circuits - the BIOWIRE and the BACT-A-SKETCH. In the Biowire project, bacterial cells create a florescent pulse that travels down a length of bacteria (i.e. a wire). The pulse is transmitted using cell-to-cell signalling, and the trick is to get the pulse to travel in one direction. The group also created micro-patterned stamps to lay down bacteria in different patterns. In the Bact-a-sketch, a lawn of cells is a film on which one can "write" using a UV pen and then "erase" using heat. The basic circuit is a genetic switch, with UV and heat inputs. The group is experimenting with several versions of switches. Both groups have several pieces of their circuit working and presented their research at the iGEM Jamboree. And some of the research is still ongoing.

This year Harvard's team consisted of 10 undergraduate students, with backgrounds in molecular and cellular biology, biochemistry, and computer science. With the help of five faculty advisors and three graduate-level teaching advisors, they devised and executed three separate projects.

1. Construction of novel DNA nanostructures for the purpose of stealth drug delivery,

2. Exploration of cell-surface targeting using interchangable and linkable aptamers (adaptamers) and Lpp-OmpA fusion vehicle for bacterial surface display.

3. Reconstitution of a circadian oscillator from cyanobacteria into E. coli,


DNA Nanobox: A Device for Stealth Drug Delivery

Project Overview

  • Our goal is to design and implement molecular containers, which can be dynamically opened and closed by an external stimulus.
  • The containers will be implemented as DNA nanostructures, which afford a significant degree of positional control and chemical versatility.
  • As an initial proof-of-concept, we plan to use our DNA containers to demonstrate controllable activation ("delivery") of anti-thrombin aptamers.
  • We expect that molecular containers could have several interesting scientific and clinical applications, such as
