Box Container Design


Evan's Denmark-like boxwithlid (single hinge)


CanDo result of Evan's boxwithlid with a double hinge: Media:Boxwithliddoublehinge.avi

  • Looks much better than with single hinge
  • See my lab notebook entry from today for more information and source files


Edited .json caDNAno file of boxwithlid_parlockmechanism and Excel file of staples for box using azobenzene sequence (F_n) lock:

NUPACK analysis of the "lock" F_n+; F_n+ with the minimal "box"; and F_n+ with the "box" and the "key" F_n+*:

Nanoparticle Chain



PAGE Gel of Handles+Ultramer Annealing Ladder

  • 100 V, 10% TBE, 45 minutes


Chain ladder gel 3 3--SYBR Gold- edited.jpg

Second Attempt at PAGE Gel of Handles+Ultramer Annealing Ladder

  • 100 V, 10% TBE, 2 hours
  • still not enough separation, but clearly an upward trend indicating more and more handles attached to ultramer
  • unclear what the white horizontal blotch near the bottom is; perhaps quenching due to too high concentration of SYBR-Gold because a lot of excess staples

PAGE Gel of Ultramer + All Nine Handles

  • 100 V, 4 hours
  • enough separation for extraction of top band, but should not have used SYBR-Gold

PAGE Gel of Ultramer + All Nine Handles

  • 100 V, 4 hours
  • SYBR-Gold that was used to stain gel is faulty

Dave's locks did not seem to work, nor did adding a select few of the equator staples

  • 1% agarose gel, 2.5 hours, 80 V

Photocleavable Spacers

Photocleavage Test 1: Using two strands with internal photocleavable spacers, directly from manufacturer-shipped tubes

  • 10% TBE PAGE gel, 15 minute UV exposure for "cleaved" strands
