Comparing Preclinical Drug-Testing Platforms: Conventional Models vs. Microphysiological Systems

Conceptual figure designed to visually compare continuous, real-time impedance monitoring with traditional end-point biological assays. The schematic enables viewers to follow the logical rationale behind the senior design project by illustrating differences in temporal resolution, data continuity, and system feedback. This visual representation supports comprehension of the project’s design motivation and experimental strategy.

Continuous Impedance Monitoring Versus Traditional Biological Assays

Conceptual timeline illustrating the gap between continuous impedance spectroscopy and traditional biological assays such as confocal microscopy and flow cytometry. The figure visually demonstrates how impedance monitoring provides continuous, high-temporal-resolution data across extended time scales, while conventional assays offer only discrete end-point or sparse measurements. This visualization supports the senior design rationale by making the motivation, limitations of existing methods, and the need for continuous monitoring visually explicit.

Electric Field Modeling and Simulated Impedance Responses Across Cell Densities

Conceptual schematic and simulated results illustrating the fundamental principles of impedance spectroscopy within a cellular microenvironment. Electric field models depict how cell membranes impede current flow, analogous to a dull blade encountering resistance, while simulated total impedance (Zₜₒₜ) responses demonstrate a monotonic increase with cell density. This figure visually translates abstract electrical concepts into an intuitive trend, enabling viewers to follow the underlying logic of the senior design approach and its projected measurement outcomes.

Rendered CAD Visualization of a PDMS-Based Microfluidic Well and Channel System

Computer-aided design (CAD) renderings created for the senior design project to visually represent the geometry, scale, and functional components of the PDMS-based microfluidic devices. The rendering highlights integrated sidewall electrodes (black) and media-filled channels and wells (red), while a U.S. quarter provides scale reference. This visualization communicates device architecture and design intent more clearly than physical prototypes alone, supporting audience understanding through a clean, simplified representation.

2D Control System Components: Cassette Assembly and Electrical Interface

Computer-aided design (CAD) visualization of the 2D control system developed for the senior design project, illustrating the cassette assembly, PDMS well, interdigitated electrode array (IDA), and electrode-to-world connection via pogo-pin electrical contacts and a 3D-printed housing. A U.S. quarter is included for scale reference. This composite visual consolidates multiple mechanical, electrical, and fluidic subsystems into a single, digestible schematic, enabling efficient communication of system architecture without detracting from the primary experimental focus.

Video walkthrough of the 3D cassette assembly developed for the senior design project, illustrating component placement, embedded magnets, integrated glass slides, and the sliding roof mechanism used to secure top and bottom layers. The video format enables clear visualization of spatial relationships and assembly logic that are difficult to convey through static images alone, making the complex three-dimensional design accessible to a broad technical audience.

Stylized BioRender illustration of a profilometer commonly used in the laboratory for surface characterization. The simplified, cartoon-style depiction was created for use in posters and presentations to visually represent profilometry methods in a clear and accessible manner. This visual abstraction supports effective communication of experimental techniques by conveying function and context without unnecessary mechanical detail.
