Multi-Scale (nano-to-device), Multi-Physics Software For Design of Nanobiosystems, Phase I

Nanobiotechnology is a rapidly advancing frontier of science with great potential for beneficial impact on society. However, successful design of these systems is an extremely complex, laborious task with large failure rates. Current models describing the molecular behavior are too slow (nanoseconds) and expensive while device design codes lack the necessary nanophysics. Our overall objective is to develop a generalized, multiscale, multiphysics CFD (continuum)-based design software where nanoscale effects of arbitrary biosystems are accurately, efficiently and seamlessly integrated with coarse-grained models carrying molecular information. To accomplish this task we propose a three-level modeling effort. First molecular calculations (Molecular Dynamics, Monte Carlo) are undertaken to elucidate the fundamental and essential molecular behavior. Next, stochastic simulation methods (Master, Fokker-Planck, or Langevin) will be seamlessly integrated with continuum approaches are developed to describe the mesoscale, fast time scale averaged behavior of these molecules. Finally, the information from the stochastic models is coupled to the continuum CFD model. In Phase I, the feasibility of this approach will be developed and demonstrated in the context of nanopore based sequencing device. The Phase II work will focus on model generalization, validation and improved usability (speed, robustness, GUI). The research is leveraged on substantial prior effort in the area.

This is a mature technology (TRL 7+) — the realistic path in is usually NASA's Technology Transfer Program: licensing an existing NASA patent, or a Space Act Agreement to use NASA facilities/expertise directly. NASA also runs a startup licensing program with no upfront fee for companies formed to commercialize a specific NASA technology.

None of these are guaranteed paths for this specific project — TechPort itself doesn't have an "apply" button. Reaching out to the contact(s) above with a specific question is usually the fastest way to find out what's actually open.
