  • Publication number: 20250116668
    Abstract: Diagnostic assay devices for detecting the presence of an analyte in a sample solution may comprise a microreactor configured to form a sample solution containing the analyte, flow the sample solution therethrough in a first direction to form an analyte-capture molecule complex, and transfer the sample solution to an absorbent strip pad configured to flow therethrough, in a second direction crossing the first direction, the sample solution including the analyte-capture molecule complex and indicate a presence of the analyte-capture molecule complex. In some embodiments the devices are configured to process a bioaerosol sample. In some embodiments the diagnostic assay devices may be multiplexed and may be used for detecting the presence of two or more analytes in a sample solution. The diagnostic devices may be used, for example, to identify the presence of one or more of SARS-Cov2, RSV, influenza A, influenza B or other pathogens in samples from patients.

  • Patent number: 9481963
    Abstract: The present invention relates to a manufacturing method of a carboxymethyl cellulose nonwoven fabric which includes the carboxymethylation of cellulose fibers and the subsequent paper-making process to prepare a carboxymethyl cellulose nonwoven fabric. Comparing with the conventional method involving carboxymethylation of a nonwoven fabric, the method of the present invention has convenience and easiness of the process and thus enables production on a large scale. Further, the carboxymethyl cellulose nonwoven fabric manufactured by the present invention is susceptible to gelation upon contact with body fluids or water and thus useful as a medical nonwoven fabric or a mask pack.
