Conoscenza delle necessarie condizioni di sintesi e le temperature di transizione vetrosa (T g s) dei polimeri viene sintetizzati sono essenziali per la fabbricazione library. Se la g T s sono sotto della temperatura ambiente, la fase di fabbricazione nanoparticelle può essere necessario effettuata in un ambiente a temperatura controllata inferiore del g T dei polimeri. Inoltre, si deve usare cautela per garantire che tutte le apparecchiature che viene a contatto con le alte temperature...

combinatorial synthesis of and high-throughput protein release from polymer film and nanoparticle libraries

Polianidridi sono una classe di biomateriali con eccellente biocompatibilità e capacità di consegna della droga. Mentre sono stati studiati estesamente con convenzionale-campione-at-a-time tecniche di sintesi, una più recente high throughput approccio è stato sviluppato consentendo la sintesi e la verifica di grandi librerie di polianidridi 1. Ciò faciliterà l&#39;ottimizzazione più efficiente e il processo di progettazione di questi biomateriali per applicazioni di rilascio di farmaci e vaccini. Il metodo in questo lavoro descrive la sintesi combinatoria di film polianidride biodegradabile e le biblioteche delle nanoparticelle e l&#39;high-throughput di rilevamento del rilascio di proteine ​​da queste librerie. In questo metodo roboticamente azionamento (figura 1), attuatori lineari e pompe a siringa sono controllati da LabVIEW, che consente un vivavoce protocollo automatizzato, eliminando errore dell&#39;utente. Inoltre, questo metodo consente la rapida realizzazione di micro-scala librerie di polimeri, rossoucing la dimensione batch mentre conseguente creazione di sistemi polimerici multivariata. Questo approccio combinatorio per sintesi polimerica facilita la sintesi di fino a 15 differenti polimeri in una quantità equivalente di tempo necessario per sintetizzare un polimero convenzionale. Inoltre, la libreria combinatoria polimero possono essere realizzati in forme geometriche vuote o proteina-loaded compresi film o nanoparticelle di dissoluzione della biblioteca polimero in un solvente e precipitazione in un non-solvente (per nanoparticelle) o da essiccazione sotto vuoto (per i film). Una volta caricato un fluorocromo coniugato proteina nelle librerie di polimeri, cinetiche di rilascio di proteine ​​può essere valutata a high-throughput usando un metodo basato sulla fluorescenza di rilevamento (figure 2 e 3) come descritto in precedenza 1. Questa piattaforma combinatoria è stato convalidato con metodi convenzionali 2 e il film polianidride e librerie nanoparticelle sono state caratterizzate con <sup&gt; 1 H NMR e FTIR. Le librerie sono stati sottoposti a screening per la cinetica di rilascio di proteine, la stabilità e antigenicità, tossicità in vitro cellulare, la produzione di citochine, espressione marcatore di superficie, l&#39;adesione, la proliferazione e la differenziazione, e in vivo e biodistribuzione mucoadesione 1-11. Il metodo combinatorio sviluppato qui permette alta produttività sintesi polimerica e fabbricazione di proteine-caricato nanoparticelle e cineteche, che può, a sua volta, essere sottoposti a screening in vitro e in vivo per l&#39;ottimizzazione delle prestazioni biomateriale.
