Disclosed herein are biosensors, which may be made from cell lysates, purified enzymes, or a combination thereof, for testing for the presence of a pathogen, such as SARS-CoV-2. The biosensor may be used in the context of a paper-based test, such as a colorimetric COVID-19 test. Methods of using the biosensor are also disclosed.

Temperature sensitive transcriptional bioswitches and related genetic circuits and in particular bandpass and/or multiplex genetic circuits, vectors, cells, compositions methods and systems are described.

An apparatus for measuring a characteristic of a sample using a centrifuge and optical components is disclosed. The centrifuge may be a standard benchtop centrifuge. The optical components may be sized and dimensioned to fit, along with the sample, inside the centrifuge.

The invention generally relates to sequencing library preparation methods. In certain embodiments, two or more template nucleic acids are joined together by a linking molecule, such as a PEG derivative. Identical copies of a nucleic acid fragment or both strands of a duplex fragment may be linked together. The linked nucleic acids are amplified, creating linked amplicons. Emulsion PCR with linked primers creates linked template nucleic acids for seeding sequencing clusters and errors can be readily identified by their presence on only one of the linked fragments.
