Blood, in all its glory, is at the center stage of life. Its circulation is necessary for the continuation of life. Its regulation is performed by multiple organs in the body. Its transportation of molecules fights diseases and replenishes nutrients. Understanding blood as a media for the body’s most critical molecular components has been central to the diagnosis of diseases and viruses throughout the centuries. The morphology of blood, dictated by the components residing within its domain— erythrocytes, leukocytes, platelets, antigens to fight foreign agents such as viruses, and many more molecules, show the potential to be represented by a patterned frequency set. Here, I present a method using acoustic tweezing, a process which utilizes a custom-built acoustic levitator to trap whole fluid samples in nodes created by ultrasound waves, to induce oscillations. Said oscillations are then analyzed spectrally, where it is found that distinct frequencies are resonated by the sample. The frequencies and the level of amplification change with sample properties, correlating changes in spectra with changes in morphological structure. Such findings led to additional work in creating models to investigate the impact of controlled changes in fluid composition on the spectra. The hope is that spectral data from oscillation patterns of whole blood and other biological fluids can be used for classification purposes in diagnostics without the excessive drawing of whole blood from patients, without the need for blood fractionation, or the need for complex and expensive laboratory analysis, such as those used in immunoassays.
