20160030343 | PREPARATION AND CHARACTERIZATION OF BONE-TARGETED VANCOMYCIN-LOADED LIPOSOMES FOR OSTEOMYELITIS TREATMENT - A treatment method, system, and compound comprise directly targets osteomyelitis-infected bone tissue with one or more surface-modified liposomes. The surface-modified liposome(s) includes an alendronate targeting moiety utilized to modify the surface of the liposome. Alendronate targets hydroxyapatite in bone tissue, wherein the surface-modified liposome further comprises encapsulated vancomycin that directly targets the hydroxyapatite in the infected bone tissue and prevents bone implant related infection. | 02-04-2016 |

20100081578 | Exchangeable sheets pre-loaded with reagent depots for digital microfluidics - The present invention provides an exchangeable, reagent pre-loaded sheets which can be temporarily applied to an electrode array on a digital microfluidic device (DMF). The substrate facilitates virtually un-limited re-use of the DMF devices avoiding cross-contamination on the electrode array itself, as well as enabling rapid exchange of pre-loaded reagents while bridging the world-to-chip interface of DMF devices. The present invention allows for the transformation of DMF into a versatile platform for lab-on-a-chip applications. | 04-01-2010 |

20120083046 | HYBRID DIGITAL AND CHANNEL MICROFLUIDIC DEVICES AND METHODS OF USE THEREOF - The present invention provides a hybrid digital and channel microfluidic device in the form of an integrated structure in which a droplet may be transported by a digital microfluidic array and transferred to a microfluidic channel. In one aspect of the invention, a hybrid device comprises a first substrate having a digital microfluidic array capable of transporting a droplet to a transfer location, and a second substrate having a microfluidic channel. The first and second substrates are affixed to form a hybrid device in which an opening in the microfluidic channel is positioned adjacent to the transfer location, so that a droplet transported to the transfer location contacts the channel opening and may enter the channel. The invention also provides methods of performing separations using a hybrid digital and channel microfluidic device and methods of assembling a hybrid digital microfluidic device. | 04-05-2012 |
