Vores origami inspirerede montage proces er alsidig og kan bruges til at syntetisere en række 3D statiske og rekonfigurerbar partikler med et bredt udvalg af materialer, former og størrelser. Yderligere, evnen til præcist mønster sensorer og elektroniske moduler på disse partikler er vigtig for optik og elektronik. I modsætning til spredte partikler dannet ved alternative fremgangsmåder, hvor mønstre er relativt upræcist, tilvejebringer denne metode et middel til at syntetisere præcist mønstrede partikler. I overfladespænding baseret samling, sikrer anvendelsen af ​​flydende forsegling hængsler, at partiklerne er godt forseglet og mekanisk stiv efter samling (ved afkøling). Tidligere har vi observeret, at sømmene er lækagesikker selv for små molekyler 39,40. Elektroafsætning af et tyndt lag af Au efter samling kan give yderligere styrke og forbedre lækagetætte karakter sømmene. Den tynde film stress baseret foldning er nyttigt til anvendelser, hvor stimuli responsive foldning er nødvendig, såsom i microgrippers der er blevet anvendt til at udføre in vitro og in vivo biologiske prøver og i pick-and-place operationer i robotteknik. Mens den specifikke metode, der beskrives her, kan bruges til at skabe omkonfigurerbare microgrippers der kun lukker én gang, kan det rette valg af materialer og metoder til at manipulere stress i dobbeltlag anvendes til også skabe gribetænger enheder, der kan omkonfigureres over flere-cykler 37, 41. Højdepunktet i brugen af ​​restspændinger til magten disse enheder er, at de ikke kræver nogen bindsler eller ledninger, og så har fremragende manøvredygtighed, så aktivering på svært tilgængelige steder. Endvidere ved et passende valg af polymere udløsere, kan stimuli responsive adfærd være aktiveret med en række stimuli, herunder enzymer 42 for at muliggøre autonom funktion af relevans for robotteknologi og kirurgi.

origami inspired self-assembly of patterned and reconfigurable particles

Der er mange teknikker, såsom fotolitografi, elektronstråle-litografi og soft-litografi, der kan bruges til præcist mønster todimensionel (2D) strukturer. Disse teknologier er modne, tilbyder høj præcision og mange af dem kan implementeres i en high-throughput måde. Vi udnytter fordelene ved plane litografi og kombinere dem med selv-sammenklappelige metoder 1-20 hvor fysiske kræfter afledt af overfladespænding eller restspændinger, der bruges til kurve eller fold plane strukturer i tre dimensioner (3D) strukturer. Dermed gør vi det muligt at masseproducere netop mønstrede statiske og omkonfigurerbare partikler, der udfordrer at syntetisere. I dette papir, visualiseret vi detalje forsøgsprotokoller at skabe mønstrede partikler, navnlig (a) permanent bundet, hule, polyedre, der selv samle og selvtætnende grund af minimering af overflade energi af fordråbede hængsler 21-23og (b) gribere, selv-fold på grund af restspændinger drevne hængsler 24,25. Det specifikke beskrevne protokol kan anvendes til at skabe partikler med samlede størrelser lige fra mikrometer til centimeter længdeskalaer. Yderligere kan arbitrære mønstre defineres på overfladerne af partiklerne af betydning for kolloid videnskab, elektronik, optik og medicin. Mere generelt begrebet selvsamlende mekanisk stive partikler med selvforseglende hængsler finder anvendelse, med nogle proces ændringer, til skabelse af partikler ved endnu mindre, 100 nm længdeskalaer 22, 26 og med en række materialer, herunder metaller 21 , halvledere 9 og polymerer 27. Med hensyn til restspændinger drevne aktivering af rekonfigurerbare grådige enheder benytter vores specifikke protokol chrom hængsler af relevans for enheder med størrelser fra 100 um til 2,5 mm. Men mere generelt, at begrebet sådan tether-fri restspændingerdrevne aktivering kan anvendes med alternative høj stress materialer såsom heteroepitaxially deponeret halvlederfilm 5,7 til muligvis skabe endnu mindre nanoskala gribning indretninger.
