The invention includes compositions for inhibiting cellular adhesion, methods of preparation of such compositions, and methods for preventing cell adhesion at a surgical site comprising application of such compositions. The compositions generally comprise a cellular adhesion inhibitory agent, such as dextran sulfate, and a crosslinked hydrogel matrix, preferentially physically entrapping the adhesion inhibitory agent. The hydrogel matrix can include a first gel component, such as an electrophilically functionalized polyethylene glycol polymer, and at least one additional gel component, preferably nucleophilically functionalized, and preferentially selected from the group consisting of polyethylene glycol polymers, polypeptides, and polysaccharides. The compositions are useful for delivering the cellular adhesion inhibitory agent to a site in need of adhesion inhibition and providing either immediate or metered delivery of the inhibitory agent.

The invention relates to active particles, including core-shell particles, having low burst, controllable, sustained release which are useful for coating seeds. The active particles can also be used in sprayable and dry formulations for treating soil or plants. The particulate coating can also contain inert organic or inorganic material. The invention also relates to methods for preparing the active particles. The methods include: adding additional material to core particles to form a shell, removing active ingredient from a core surface to create an active-depleted shell, and crosslinking the outer layers of a core to form a shell.

A drive rod in a solid material dispenser is linearly movable along, and rotationally movable around, an axis direction. A central rod is attached to the drive rod and drivable by the drive rod to rotate around the axis direction with the drive rod. A solid material container has one or more compartments to store solid materials to be dispensed. A switch valve is rigidly attached to the central rod and drivable by the central rod to rotate around the axis direction with the central rod. A container bottom of the solid material container comprises one or more first component shapes that form one or more first interstitial void spaces. The switch valve comprises one or more second component shapes that form one or more second interstitial void spaces.

An automated toxicity assessment apparatus includes multiple sample plates each configured to hold test wells for holding a test solution comprising a test compound and a test organism. A dispense head holds dispense tips for dispensing test solutions into the test wells in one sample plate at each time. An electronic detector can capture an image of a test solution in one of test wells on a sample plate to establish a dose-response curve for the test organism. A carousal system rotates a first sample plate to a first position under the dispense head to allow the plurality of dispense tips to dispense solutions into the test wells on the first sample plate. The carousal system rotates the first sample plate to a second position to allow the electronic detector to capture an image of a test solution in the one of test wells on the first sample plate.
