The present disclosure provides for analysis systems that are configured to extract a fluid sample from a fluid (e.g., aqueous solution) in a reactor (e.g., bioreactor) at a first rate and then flow the fluid sample to a sensor system at a second rate to analyze the fluid sample. The sensor system can detect the presence and/or concentration of molecules (e.g., biomolecules such as biomarkers (e.g., metabolites, proteins, peptides, cytokines, growth factors, DNA, RNA, lipids) and cells of different types and cell properties, e.g., mechanical stiffness, etc.)). The data obtained can be used by a feedback control system to modify, as needed, the conditions in the reactor to enhance the productively of the reactor.

Analysis system and methods of use thereof

Disclosed herein are specimen imaging systems, comprising: a sample stage in a vacuum environment, the sample stage configured to support a specimen; an electron beam generator configured to focus an electron beam on a first predetermined location on the specimen; a nanospray dispenser configured to dispense a nanospray onto a second predetermined location on the specimen; a mass spectrometer; and an extraction conduit configured to extract a plume of charged particles generated as a result of contact between the nanospray and the specimen and deliver the charged particles to the mass spectrometer. The system can create a topological and chemical map of the specimen by analyzing at least a portion of the specimen with a mass spectrometer to determine a chemical composition of the specimen at the second predetermined location and analyzing at least a portion of the specimen with the electron beam to determine a surface topology.

Specimen imaging systems and methods

SMS probe imaging systems, methods of use thereof, and the like are disclosed. Embodiments of the present disclosure can use direct interrogation of objects (e.g., cells or tissue) within a small pool/droplet of liquid, optional thermal, mechanical, electrical, optical and chemical manipulation, followed immediately by liquid sampling, optional sample conditioning, and soft ionization of biomolecules.
