Phantoms are generally used for vitro measurements of non-invasive blood glucose measurements, they comprises of aqueous solution with water, fat and muscles of animal bodies. In vivo tests for blood sugar monitoring, the human finger web which is normally around 6.5mm is used. so, approximately the same amount of viscous fluid is possible by these glucose phantoms (1).
Phantoms controls the experimental parameters and thereby used for many critical tests on heamoglobin and tissue tumors.
Phospate buffer(0.1 M,pH 7.35) with added fat from animal sources makes the phantom ready for tests provided of having thickness in desired range.
