“…The sensor could detect 10–15 µm of iron particles and 65–70 µm of copper particles in the oil. Similar to the differential resistive pulse sensor (RPS), Yang et al [ 108 ] proposed an inductive sensor based on differential detection that employs two induction coils embedded in a single excitation coil. By reverse connecting the two induction coils with identical parameters, the differential signal is obtained, thereby suppressing common mode interference and eliminating ambient noise effects to produce an ultra-low noise sensor.…”

Particle counting serves as a pivotal constituent in diverse analytical domains, encompassing a broad spectrum of entities, ranging from blood cells and bacteria to viruses, droplets, bubbles, wear debris, and magnetic beads. Recent epochs have witnessed remarkable progressions in microfluidic chip technology, culminating in the proliferation and maturation of microfluidic chip-based particle counting methodologies. This paper undertakes a taxonomical elucidation of microfluidic chip-based particle counters based on the physical parameters they detect. These particle counters are classified into three categories: optical-based counters, electrical-based particle counters, and other counters. Within each category, subcategories are established to consider structural differences. Each type of counter is described not only in terms of its working principle but also the methods employed to enhance sensitivity and throughput. Additionally, an analysis of future trends related to each counter type is provided.
