A novel hydrogel delivery systems useful for encapsulating and releasing pharmaceuticals or chemicals is disclosed where water soluble polymers containing crosslinker repeating units that associate or dissociate with complementary crosslinking repeating units or separate linkers to reversibly crosslink the hydrogel. In an exemplary embodiment, a DNA crosslinked hydrogel displays photoreversibility. An exemplary hydrogel delivery system comprises DNA polymer conjugates, wherein complementary DNA sequences are crosslinked with polymer chains and hybridization of the DNA sequences is controlled by photoresponsive moieties. Such hydrogels can be used to release drug molecules and/or other therapeutic reagents. The exemplary hydrogel employs photosensitive azobenzene moieties that are incorporated into the DNA crosslinker units. The azobenzene moieties respond to different wavelengths of light so that the state of azobenzene isomerization is induced by the proportion of visible and UV light irradiated. The isomer state of the azobenzene dictates whether the complementary DNA sequences hybridize to cross link the DNA polymer conjugates. Thus, irradiation of light (visible or UV) can transform the hydrogel network between a sol and any of multiple gel states to regulate the degree of crosslinking between complementary DNA sequences and, therefore, provide a profile of release of a hydrogel encapsulated pharmaceutical or other chemical.

The present invention provides a latch assembly of the type commonly used on commercial vehicles which is simple to manufacture and has few parts. The latch assembly secures a closure element, or striker, in either of two secure positions by means of independently operable dual linear latch bolts and may be closed when the locking mechanism is in a locked position, to facilitate ease of operation and to prevent damage to the latch. The latch bolts are releasable by operation of a remotely located handle actuated rotary latch mechanism.

A magnetic connector assembly has a female connector with spring-loaded conductive pins slightly protruding inside a recess or cavity in the female connector's body. A corresponding male connector has a protrusion on its body with conductive pins slightly indented into the protrusion's surface. The protrusion on the male connector is sized and shaped to fit into the cavity in the female connector such that the male connector's pins engage the pins of the female connector, allowing for electrical communication across the connector assembly. Magnets on the male and female connectors secure them in a correct orientation. A unique shape ensures proper alignment of the pins and prevents the connection of incompatible devices.

A method for manufacturing a bit patterned magnetic media for magnetic data recording. The method includes selectively depositing a self assembled monolayer over a seed layer and then oxidizing the deposited self assembled monolayer. The self-assembled monolayer can be deposited by use of a stamp to form a pattern covering areas where a non-magnetic segregant (such as an oxide) is to be formed and openings where a magnetic material is to be formed. A magnetic alloy and a segregant (such as an oxide) are then co-sputtered. The magnetic alloy grows only or selectively over the seed layer, whereas the segregant grows only or selectively over the oxidized self-assembled monolayer.
