Diode and Active Negative Resistance Behaviors of Helminth Eggs As a Novel Identification/Differentiation Probe

Helminths have always been studied as one of the critically annoying pathogens of parasite classes due to their adverse effects on the ecosystem of human life. They have the potency to negatively affect their hosts as points of disease, infection, cancer, and death, but in this study, we found interesting electronic properties in , (with and without larvae), , , and eggs. This claim is attributed to some surprising characteristics such as significant diode behavior [forward bias, 5.36-11.17 (±0.01) V, versus the ground, GND] and backward bias (-45.0 to -125.0 (±7.0) V, versus the GND) and highly active negative resistance (-2.59 to -7.11) × 10 (±1.5) Ω in the AC mode. These traits were measured by the "blind patch-clamp, single-unit recording" methodology using a three-microelectrode system, implanted onto each tested egg under giga ohm sealed conditions (6.28 ± 0.02 GΩ cm and n = 4). All the characteristic parameters were simultaneously attributed to the helminth egg structure by acceptable reproducibility (percentage of relative standard deviation: > 5%) and high enough rectitude with enough differentiation in their magnitudes, relatively. The reliability of these results was further confirmed using multiple calibrated techniques such as alternative/direct current voltammetry. Also, the significant role of water molecules as the key medium in creating these properties is evaluated qualitatively. In addition, the study aims at introducing these interesting parameters as a new approach to the fabrication of bio-based electronic elements, which are considered as a novel class of helminth egg-detection and -identification probes.
