\nEl material m\u00e9s utilitzat per treballar amb pinces \u00f2ptiques \u00e9s el di\u00f2xid de silici. En la present investigaci\u00f3 s\u2019ha estudiat la polaritzabilitat, la freq\u00fc\u00e8ncia d\u2019oscil\u00b7laci\u00f3 i la constant el\u00e0stica de diferents nanopart\u00edcules atrapades en un sistema de pinces \u00f2ptiques. Els materials emprats han sigut l\u2019\u00f2xid d\u2019alumini, el di\u00f2xid de titani, el di\u00f2xid d\u2019hafni i, evidentment, el di\u00f2xid de silici.
\nCombinant mitjans te\u00f2rics i experimentals s\u2019ha comprovat que \u00e9s possible atrapar part\u00edcules de mida comparable de materials diferents del di\u00f2xid de silici i que, en determinades condicions, certes nanopart\u00edcules oferiran millors prestacions que les d\u2019aquest. Ara b\u00e9, per aplicar els altres materials de manera eficient, caldr\u00e0 perfeccionar el disseny de les seves nanopart\u00edcules.<\/span><\/span><\/p>\n
