    Abstract: Described herein are engineered microbe-targeting or microbe-binding molecules, kits comprising the same and uses thereof. Some particular embodiments of the microbe-targeting or microbe-binding molecules comprise a carbohydrate recognition domain of mannose-binding lectin, or a fragment thereof, linked to a portion of a Fc region. In some embodiments, the microbe-targeting molecules or microbe-binding molecules can be conjugated to a substrate, e.g., a magnetic microbead, forming a microbe-targeting substrate (e.g., a microbe-targeting magnetic microbead). Such microbe-targeting molecules and/or substrates and the kits comprising the same can bind and/or capture of a microbe and/or microbial matter thereof, and can thus be used in various applications, e.g., diagnosis and/or treatment of an infection caused by microbes such as sepsis in a subject or any environmental surface. Microbe-targeting molecules and/or substrates can be regenerated after use by washing with a low pH buffer or buffer in which calcium is insoluble.

    Abstract: The present invention is directed to a method of patterning materials, such as proteins, on a contoured surface by depositing them onto protrusions on the surface and to a cell containment device that may be constructed by this method. In one embodiment, the present invention is directed to a method of selectively depositing a material on a substrate including a contoured surface including a protrusion and a recess. The method includes applying a first fluid to the contoured surface of the substrate and allowing the first fluid to distribute across a portion of the contoured surface such that the first fluid contacts the protrusion and not the recess. The method also includes allowing a first material to deposit on the substrate where the substrate is in contact with the first fluid. Optionally, this method may further include applying a second fluid to the contoured surface of the substrate, allowing the second fluid to distribute across a portion of the contoured surface such that the second fluid contacts the recess, and allowing a second material to deposit on the substrate where the substrate is in contact with the second fluid. Optionally, the method may still further include applying a third fluid to the contoured surface of the substrate, allowing the third fluid to distribute across a portion of the contoured surface, and allowing a third material with an affinity for one of the first material and the second material to deposit on the substrate only where the one of the first material and the second material is deposited. In one embodiment of this method the first material is a cytophobic material, the second material is a cytophilic material and the third material is a cell. In another embodiment, the present invention is directed to a cell containment device, including a substrate having a contoured surface, a recess in the surface of the substrate, a cytophobic material connected to the surface of the substrate outside the recess and a cytophilic material connected to the recess.

    Abstract: An organomimetic device comprising: a. a first microchannel height-defining layer having a bottom surface and a first microchannel disposed in the bottom surface wherein the first microchannel height-defining layer comprises: i. a first lamination layer having a first microchannel aperture therein, wherein thickness of the first lamination layer defines the height of the first microchannel; and ii. a first sealing layer disposed on top of the first lamination layer, wherein the first sealing layer provides a top closure of the first microchannel aperture, thereby forming the first microchannel; b. a second microchannel height-defining layer having a top surface and a second microchannel disposed in the top surface; and c. a membrane layer having a membrane portion, the membrane layer being laminated between the bottom surface of the first microchannel height-defining layer and the top surface of the second microchannel height-defining layer, wherein a first surface portion of the membrane portion provides a lower boundary of the first microchannel and a second surface portion of the membrane portion provides an upper boundary of the second microchannel; and wherein at least a portion of the first microchannel is aligned with at least a portion of the second microchannel on an opposite side of the membrane portion. 242 200 244 207 206 202 209 230 -- ,232

    Abstract: Disclosed herein are devices and methods for generating orthotopic models of cancer. The devices and methods include providing a microfluidic device having a body, the body including a first microchannel separated from a second microchannel by an at least partially porous membrane, the membrane having a first side facing the first microchannel and a second side facing the second microchannel, seeding the first side of the membrane with healthy cells and cancer cells such that the cancer cells are seeded with a differentiated tissue layer, and culturing the healthy cells and the cancer cells within the microfluidic device by flowing medium through one or more of the first and second microchannels with or without endothelium in the second channel.
