Label-free analysis of physiological hyaluronan size distribution with a solid-state nanopore sensor.
Abstract: Hyaluronan (or hyaluronic acid, HA) is a ubiquitous molecule that plays critical roles in numerous physiological functions in vivo, including tissue hydration, inflammation, and joint lubrication. Both the abundance and size distribution of HA in biological fluids are recognized as robust indicators of various pathologies and disease progressions. However, such analyses remain challenging because conventional methods are not sufficiently sensitive, have limited dynamic range, and/or are only semi-quantitative. Here we demonstrate label-free detection and molecular weight discrimination of HA with a solid-state nanopore sensor. We first employ synthetic HA polymers to validate the measurement approach and then use the platform to determine the size distribution of as little as 10 ng of HA extracted directly from synovial fluid in an equine model of osteoarthritis. Our results establish a quantitative method for assessment of a significant molecular biomarker that bridges a gap in the current state of the art.

This research article discusses a new method for detecting and measuring the molecular weight of Hyaluronan, a critical molecule involved in many bodily functions, using a solid-state nanopore sensor. This technique shows promise for assessing variations in Hyaluronan levels and size distribution, which can indicate different diseases or their progression.
Introduction
- The focus of this research is Hyaluronan or hyaluronic acid (HA), a molecule prevalent in the body and performs many physiological functions – it contributes to tissue hydration, inflammation response, and joint lubrication.
- HA level and size distribution in body fluids can serve as indicators of different diseases and their progression. Nonetheless, these analyses have always been a challenge as traditional methods lack sensitivity, have a restricted dynamic range, and only offer semi-quantitative results.
Methodology
- The researchers propose a method for detecting and determining HA’s molecular weight without any labels, using a solid-state nanopore sensor.
- They first used synthetic HA polymers to verify this measurement method.
Results & Applications
- Having validated their approach with synthetic HA, they applied the platform to ascertain the size distribution of HA (minimum 10 ng) that was directly extracted from synovial fluid, using a horse model of osteoarthritis.
- Their results offer a quantitative method for evaluating a crucial molecular biomarker, thereby, addressing a gap in the current understanding and study.
- This research holds potential in disease detection and monitoring as variations in hyaluronan levels and size can indicate diverse diseases or their progression states.
