The laminated film includes a flexible substrate, an organic layer disposed in contact with at least one surface of the substrate, and a thin film layer disposed in contact with the surface of the organic layer; the organic layer containing an acrylate resin; the thin film layer containing Si, O, and C; and the laminated film satisfying all of the following requirements (i) to (iii) in a silicon distribution curve, oxygen distribution curve, and carbon distribution curve in the thin film layer: (i) the atomic number ratio of Si, the atomic number ratio of O, and the atomic number ratio of C satisfy the requirement represented by the following formula (1) in 90% or more of the area of the thin film layer in the film thickness direction of the thin film layer;
(Atomic number ratio of O)>(Atomic number ratio of Si)>(Atomic number ratio of C) (ii) the carbon distribution curve has at least one extreme value; and (iii) the absolute value of a difference between the maximum value and the minimum value of the atomic number ratio of carbon in the carbon distribution curve is 0.05 or more.
SEMIPERMEABLE ULTRATHIN POLYMER MEMBRANES
A semipermeable ultrathin polymer membrane is a microfluidic device that comprises a substantially optically transparent polymer film having a surface area to thickness ratio of at least 1,000,000:1, and an array of precisely spatially ordered pores of a user-selected diameter defined therethrough. Such membranes can be fabricated by providing a mold having a patterned array of nanoholes femtosecond laser ablated in a surface thereof; applying a first polymer solution onto the mold surface so that the first polymer solution infiltrates the nanoholes; allowing the first polymer solution to dry and form a replica of the mold having a plurality of freestanding nanoneedles extending from a surface of the replica; removing the replica from the mold; coating the replica surface with a second polymer solution; drying the second polymer solution to form a porous polymer film; and dissolving the replica in a solvent to release the film from the replica as a semipermeable ultrathin polymer membrane. Also disclosed are multi-chambered microfluidic devices for studying cell biology in vitro that incorporate one or more such semipermeable ultrathin polymer membranes.
Use of UV-radiation-hardenable polyurethane resins for producing solar laminates

Methods to dismantle hermetically sealed chambers
Embodiments generally relate to apparatus and methods for dismantling a hermetically sealed chamber. In one embodiment, an apparatus facilitating the opening of a hermetically sealed chamber in a device comprises a fixture configured to hold the device, and a system configured to create sufficient tensile or shear stress at a bond interface of the seal to open the seal under controlled conditions. In one embodiment, a method for opening a hermetic seal between first and second elements forming a chamber in a microfluidic chip comprises using a release technique creating sufficient tensile or shear stress at a bond interface of the seal to open the seal under controlled conditions. The release technique comprises introducing a tool to the vicinity of the interface without any contact between the tool and any material within the chamber. The breaking of the seal results in the complete separation of the first and second elements.

Flexible packaging structure with a built-in opening and reclose feature
A flexible packaging laminate is formed to have a built-in opening and reclose feature by forming the laminate as a two-part structure having an outer structure joined in face-to-face relation with an inner structure. Score lines are formed in both structures to enable an opening to be formed through the laminate by lifting an opening portion (e.g., a flap or the like) of the two structures out of the plane of the laminate. The score line through the outer structure defines a larger opening than the score line through the inner structure, such that a marginal region of the outer structure extends beyond the edge of the opening portion of the inner structure. A pressure-sensitive adhesive is used to re-adhere the marginal region to an underlying surface of the inner structure adjacent the opening through the laminate.
