Water-responsive actuators and methods for creating water responsive actuators are disclosed. In some embodiments, the disclosed subject matter includes a first layer, for example a plastic tape, and a second layer, for example bacterial spores and cured adhesive. The second layer can be created in a pattern. The pattern can include joints, which can contract when exposed to dry air and can thereby bend the actuator, and can expand when exposed to humid air and thereby return the actuator its original position.

Provided herein are mycelium materials and methods for production thereof. In some embodiments, a mycelium material includes: a cultivated mycelium material including one or more masses of branching hyphae, wherein the one or more masses of branching hyphae may be disrupted and/or a bonding agent may be combined with the cultivated mycelium material. Methods of producing a mycelium material are also provided.

There is provided a cell recovery method for recovering cells which are cultured in at least one container containing a liquid medium and adhere to an inner surface of the container, the method including performing: a medium discharge step of discharging the liquid medium from the container; a peeling liquid supply step of supplying a peeling liquid for peeling the cells from the inner surface of the container to the container; a peeling liquid discharge step of discharging the peeling liquid from the container before the cells are completely peeled from the inner surface of the container; a waiting step of waiting until the cells are peeled by action of a residual peeling liquid; and a recovery liquid supply step of supplying a recovery liquid for recovering the cells to the container.

The present application relates to a microfluidic system and its method for use for the separation of motile sperm from immotile sperm or motile bacteria from immotile bacteria. The system includes a housing having a first end, and a second end, with a passage connecting the first and second ends. There is an inlet at the first end of the housing for charging fluids into the passage and an outlet at the second end of said housing for discharging fluids from the passage. There are one or more corrals within the passage, each of the corrals including a closed side and a partially open side. The closed side of the corrals is closer to the first end than the partially open side, with the closed side and partially open side defining between them a confinement region suitable for retaining motile sperm or motile bacteria.

Described herein are isolated cell culture components such as, e.g., biologics and/or lipids, and methods for isolating cell culture components from a liquid cell culture medium. Methods of the present invention may include contacting a dehydration composition and a liquid cell culture medium comprising a target component to form a mixture; forming an at least partially dehydrated component in the mixture; and separating the at least partially dehydrated component from the mixture, thereby providing an isolated component. In some embodiments, the isolated component comprises the at least partially dehydrated component. In some embodiments, the isolated component is present in a composition (e.g., liquid phase) separated from the at least partially dehydrated component.
