We identified critical design parameters needed for ideal de novo nanopore sensors with atomistic engineerability and reproducibility. This work integrates a wide array of de novo protein, with varying levels of stability, selectivity, and sequencing applicability, culminating in demonstrating ssDNA translocation using designed protein integrated into SiNx. Chapter 1 provides an introduction into nanopore sequencing, biological and solid-state nanopore systems, protein design through deep learning diffusion, and surface chemistry. Chapter 2 summarizes the work done in creating custom 3D printed microfluidics, control measurements for the hybrid system, CPD and ICR applications for surface coating analysis. Chapter 3 discusses the selection of protein from the early iterations of our design campaigns and identifies the primary parameters that are needed for stable insertions. Chapter 4 details improvements build off of the preliminary work in chapter 3 to demonstrate the translocation of small charged molecules of PAA and ssDNA. These results will provide insights towards rational design for hybrid sequencing platforms with stable integration of AI-enabled designer protein with solid-state platforms. With time, this work paves the way for atomically reproducible, purposefully engineered, and highly parallelized multi-omic hybrid nanopore system.application/pdfen-USnoneDe novo protein designNanopore sequencingSolid-state nanoporePhysicsBiophysicsPhysicsThesis
