An array of membranes comprising amphipathic molecules is formed using an apparatus comprising a support defining an array of compartments. Volumes comprising polar medium are provided within respective compartments and a layer comprising apolar medium is provided extending across the openings with the volumes. Polar medium is flowed across the support to displace apolar medium and form a layer in contact with the volumes, forming membranes comprising amphipathic molecules at the interfaces. In one construction of the apparatus, the support that comprises partitions which comprise inner portions and outer portions. The inner portions define inner recesses without gaps therebetween that are capable of constraining the volumes comprising polar medium contained in neighbouring inner recesses from contacting each other. The outer portions extend outwardly from the inner portions and have gaps allowing the flow of an apolar medium across the substrate.

Apparatuses and methods are described herein for processing polynucleotides in a sealed path environment. The apparatuses include optical sensors to monitor operations and to track material usage for good manufacturing practice.

The inventive subject matter provides methods for reproducibly fabricating hydrogel-based organ and tumor models inside multi-well plates. A hydrogel precursor, which can include cells, is instilled into a well. A pillar is inserted into the well to contact the hydrogel precursor with a surface that can be shaped or textured to provide a desired surface configuration or contour, for example that of a desired organoid or tumor feature. The hydrogel precursor is polymerized and the pillar removed. A second hydrogel precursor, which can contain a different cell type, is then instilled into the well and a second pillar, which can have a different configuration or texture, inserted. Subsequent polymerization generates a second hydrogel portion within the well. Polymerization can be carried out by photopolymerization. Different wells can be aligned with different, individually controlled light sources or a single, collimated light source.

De novo synthesized large libraries of nucleic acids are provided herein with low error rates. Further, devices for the manufacturing of high-quality building blocks, such as oligonucleotides, are described herein. Longer nucleic acids can be synthesized in parallel using microfluidic assemblies. Further, methods herein allow for the fast construction of large libraries of long, high-quality genes. Devices for the manufacturing of large libraries of long and high-quality nucleic acids are further described herein.

The present invention provides a rotating microfluidic device capable of combining portions of various liquids into a single droplet, thus generating millions of droplets with differing compositions.

The present disclosure provides biochips and methods for making biochips. A biochip can comprise a nanopore in a membrane (e.g., lipid bilayer) adjacent or in proximity to an electrode. Methods are described for forming the membrane and inserting the nanopore into the membrane. The biochips and methods can be used for nucleic acid (e.g., DNA) sequencing. The present disclosure also describes methods for detecting, sorting, and binning molecules (e.g., proteins) using biochips.

Provided herein are compositions, devices, systems and methods for generation and use of biomolecule-based information for storage. Further provided are devices-having addressable electrodes controlling polynucleotide synthesis (deprotection, extension, or cleavage, etc.) The compositions, devices, systems and methods described herein provide improved storage, density, and retrieval of biomolecule-based information.

The inventive subject matter provides an apparatus for reproducibly fabricating hydrogel-based organ and tumor models inside multi-well plates. For example, tumor models made using the inventive apparatus can be used for studying the progression of cancer, cancer diagnostics, and therapeutic screening. A mold controls the thickness of each hydrogel layer. A photomask controls the size and shape of each hydrogel layer, allowing the hydrogel diameter to be smaller than the diameter of each well so that liquid media can be exchanged around both the sides and top of the hydrogels. A holder aligns the photomask with the multi-well plate, and polymerization is initiated by a light source.
