Summary
A new multi-sample Light-Assisted Drying (LAD) platform enables high-throughput stabilization of biologics. This innovative method uses near-infrared laser radiation for room-temperature storage, reducing cold-chain dependence.
Area of Science:
- Biotechnology
- Materials Science
- Chemical Engineering
Background:
- Light-Assisted Drying (LAD) is an emerging technique for stabilizing biologics like vaccines and therapeutics.
- Current LAD methods are limited to single-sample processing, hindering scalability.
- Effective biologic stabilization requires methods that minimize thermal degradation and cold-chain logistics.
Purpose of the Study:
- To develop and validate a multi-sample Light-Assisted Drying (LAD) platform for high-throughput biologic stabilization.
- To investigate the feasibility of using 1,064 nm near-infrared laser radiation for scalable, room-temperature drying of biologics.
- To demonstrate the preservation of biologic integrity and function after multi-sample LAD processing.
Main Methods:
- Integrated optical (LightTools) and thermal (lumped-parameter) modeling to design a multi-sample LAD system.
- Developed a prototype system capable of processing vertically stacked samples using near-infrared laser radiation.
- Validated the system's performance using Human Immunoglobulin G (Human IgG) as a model biologic, assessing drying time, temperature, and functional integrity.
Main Results:
- Optical simulations confirmed efficient energy reuse across vertically stacked samples (<10% absorption per sample).
- Thermal modeling predicted successful drying of a three-sample stack within 100 minutes at peak temperatures below 33 °C.
- Experimental results showed Human IgG retained full binding affinity (ELISA) and structural integrity (DSC) after multi-sample LAD.
Conclusions:
- The developed multi-sample LAD system is feasible for high-throughput processing of biologics.
- This technology offers a scalable solution for room-temperature biologic stabilization, reducing reliance on cold-chain infrastructure.
- The findings represent a significant advancement toward the industrial-scale application of LAD for biologic preservation.
