Fa temps vaig fer una entrada sobre origami real d’ADN, un experiment amb aquesta biomacromolècula. Ara amb ADN s’han fet també nanocapses fent servir tècniques orgimàmiques, segons Chemistry World.
El més prometedor, a part de la pròpìa fabricació d’aquestes nanocapses de 30 nanometres d’aresta (n’hi cabrien 30.000 en un mil.límetre), és que s’hi pot posar coses a dins, des d’enzims a virus. Per exemple, es podrien fer servir com a nanocalculadora, per proporcionar de forma control.lada fàrmacs, i com a sensor:
Thinking inside the box
Kjems reveals that the group have already had some success with putting cargo inside the boxes, including enzymes and quantum dots. ‘It’s quite big (about 30nm) inside – it could fit virus particles or quite big enzymes and other macromolecules.’ In terms of applications, Kjems can foresee three main purposes for the box: ‘One is as a calculator or logic gate; the second is for controlled release, for example of drugs, in response to external stimuli; and the last is as a sensor – where the thing you are sensing causes the box to open or close and give a readout.’
