The present invention provides an automated modular system and method for production of biopolymers including DNA and RNA. The system and method automates the complete production process for biopolymers. Modular equipment is provided for performing production steps with the individual modules arrange in a linear array. Each module includes a control system and can be rack mounted. One side of the array of modules provides connections for power, gas, vacuum and reagents and is accessible to technicians. On the other side of the array of modules a robotic transport system is provided for transporting materials between module interfaces. The elimination of the requirement for human intervention at multiple steps in the production process significantly decreases the costs of biopolymer production and reduces unnecessary complexity and sources of quality variation.

Systems, methods, and devices for generating radionuclides for use in production of radiopharmaceuticals; synthesizing the radionuclides generated and removing any unwanted products; measuring the quantity and activity level of the synthesized radionuclides; distributively delivering the radionuclides in appropriate quantities to modular cassette synthesis units in a modular cassette subsystem for contemporaneous/parallel production of radiopharmaceutical output and that allow reuse and/or quick, safe, and disposable replacement of portions of the subsystem; delivering non-radionuclide components to the modular cassette synthesis units as part of production of radiopharmaceutical output; measuring the quantity and activity level of each stream of radiopharmaceutical output; purifying the radiopharmaceutical output; dispensing individual doses in sterile vial(s); automatically producing labeling and dose related information; performing automated quality control on extracted samples of produced radiopharmaceutical output; and providing software and hardware controls for overall and sub-portion operation for optional remote data collection, communication, and/or control.

Acid gas compounds are removed from a process gas such as, for example, syngas or natural gas, by flowing a feed gas into a desulfurization unit to remove a substantial fraction of sulfur compounds from the feed gas and flowing the resulting desulfurized gas into a CO.sub.2 removal unit to remove a substantial fraction of CO.sub.2 from the desulfurized gas.

Provided is a fabrication method of print head of MCM device formed micro patterned air gap capable of picoliter-scale droplet printing, and more particularly, is characterized in that comprising preparing silicon wafer 10 washed by piranha solution at step A, stacking silicon nitride films 20 and 20 up front surface and back surface of prepared silicon wafer at step B, drying after applying photoresists 30 and 30 to top surface and bottom surface of the silicon nitride film 20 and 20 at step C, removing partially the photoresists through pre-determined pattern by irradiation of ultraviolet after arranging photomask 40 formed through pre-determined pattern in any one side of the photoresists 30 and 30 at step D, forming sample droplet storage space opening by removing silicon nitride film 21 contacted to photoresists removed by pre-determined pattern at step E, removing the photoresists 30 and 30 stacked up the silicon nitride film 20 and 20 at step F, forming sample droplet storage space 50 by etching the silicon wafer at step G, and forming sample droplet opening 60 by irradiating ultrasonic waves at step H.

Provided are methods of producing size-selected nucleic acid libraries. The methods include contacting a nucleic acid sample and a nucleic acid binding reagent including an affinity tag, under conditions in which nucleic acids of less than a desired length are substantially bound to the nucleic acid binding reagent and nucleic acids of the desired length are substantially not bound to the nucleic acid binding reagent. The conditions include the duration of the contacting, the concentration of the nucleic acid binding reagent, or both. The methods further include separating, using the affinity tag, the nucleic acids of less than the desired length bound to the nucleic acid binding reagent from the nucleic acids of the desired length not bound to the nucleic acid binding reagent, to produce a size-selected nucleic acid library. Compositions and kits that find use, e.g., in practicing the methods of the present disclosure, are also provided.
