20210283201 · 2021-09-16 ·

The present specification describes methods and systems for treating a patient having a SARS-CoV-2 virus load greater than a predefined threshold. A patient is assessed to determine if the patient has the SARS-CoV-2 virus load greater than the predefined threshold. If the patient has the SARS-CoV-2 virus load greater than the predefined threshold, a volume of plasma is removed from the patient. In a plasma delipidation system, the volume of plasma is mixed with an extraction solvent to delipidate at least some of the SARS-CoV-2 viruses in the patient's SARS-CoV-2 virus load, thereby causing one or more modifications to the SARS-CoV-2 viruses. The extraction solvent is removed from the plasma and the plasma is administered with the at least some of the delipidated SARS-CoV-2 viruses to the patient.

A method of sampling and testing for SARS-COV-2 virus in nasal and nasopharyngeal fluid using a plurality of microfluidic channels with a plurality of integrated electrodes in the microfluidic channels to detect the virus. In one example embodiment, a plurality of antibodies are fixed on a surface of at least one electrode by positive dielectrophoresis that increases the sensitivity of detection. Viral antigens bind to the antibodies separating from the fluid thereby signally that the virus is present as evidenced by the detection of the antigens. Sampling by microfluidic channels is more comfortable to a patient because microfluidic channels are soft, flexible and narrow compared to swabs. Another example embodiment of a method using microfluidic channels for collecting tears or saliva to determine blood glucose levels using a smartphone that has been modified to incorporate external filters quantitate glucose levels is also described.

Method and process to make and use cotton-tipped electrochemical immunosensor for the detection of corona virus
11035817 · 2021-06-15 · ·

A method and process to make and use cotton-tipped electrochemical immunosensor for the detection of corona viruses is described. The immunosensor were fabricated by immobilizing the virus antigens on carbon nanofiber-modified screen printed electrodes which were functionalized by diazonium electrografting and activated by EDC/NHS chemistry. The detection of virus antigens were achieved via swabbing followed by competitive assay using fixed amount of antibody in the solution. Ferro/ferricyanide redox probe was used for the detection using square wave voltammetric technique. The limits of detection for our electrochemical biosensors were 0.8 and 0.09 pg/ml for SARS-CoV-2 and MERS-CoV, respectively indicating very good sensitivity for the sensors. Both biosensors did not show significant cross reactivity with other virus antigens such as influenza A and HCoV, indicating the high selectivity of the method.
