Publication number: 20220339627Abstract: Aspects of this disclosure relate to systems, devices, and methods for the transfer of fluid to fluidic receptacles. In some embodiments, the fluid contains one or more molecules (e.g., one or more peptides, proteins, and/or nucleic acids) of interest, and the fluidic receptacle includes an integrated device. In certain embodiments, the one or more molecules can be immobilized on the integrated device for subsequent analysis (e.g., sequencing). Certain aspects of the present disclosure are directed towards systems and methods that can, in some instances, enhance the immobilization of the one or more molecules on the integrated device, e.g., by improving a rate of sample interaction with the integrated device. Through the use of systems, devices, and methods of the instant disclosure, target molecules may be more readily sequenced or prepared for sequencing.Type: ApplicationFiled: April 20, 2022Publication date: October 27, 2022Applicant: Quantum-Si IncorporatedInventors: Xiaoxiao Ma, Jonathan C.
