Market Driver

Rising Demand for Real-Time Kinetic Analysis in Biologics Development

Growing reliance on real-time kinetic analysis is driving market growth in biologics and antibody discovery. Label-free techniques such as Surface Plasmon Resonance (SPR) and Biolayer Interferometry (BLI) are becoming essential for evaluating molecular interactions with high precision. 

These technologies support critical functions such as affinity profiling and quality control, while high-throughput SPR platforms enable large-scale screening during discovery and development. 

Improved sensor chemistries and advanced software are reducing analysis times, making candidate selection more efficient and less risky. By accelerating screening and improving accuracy, real-time kinetic analysis is strengthening decision-making across research and Chemistry, Manufacturing, and Controls (CMC) workflows.

• In January 2025, Carterra Inc. shipped its first Carterra Ultra biosensor platform. The new instrument, which used gold-standard Surface Plasmon Resonance (SPR) detection, enabled high-throughput screening for both small and large molecules. This technology allowed investigators to conduct molecular analysis at an industrial scale for a range of applications, including fragment-based lead discovery and protein-protein interactions.

Market Challenge

 Regulatory and Validation Barriers

A significant challenge impeding the progress of the label free detection market is that many LFD systems are being marketed as “Research Use Only” (RUO). This restricts their deployment in regulated diagnostic applications and complicates the translation of validated research protocols into Good Manufacturing Practice (GMP) environments. Moreover, adoption in clinical workflows is slowed, and regulatory compliance and technology transfer become more complex.

To address this challenge, companies are establishing analytical validation protocols that align with ICH guidance and ensure compliance with RUO labeling. They are testing label-free methods to meet international drug testing rules, using approved materials for reliability, and implementing secure software that tracks all changes and maintains accurate records to meet regulatory standards.

Market Trend

Rising Adoption of Automated, High-Throughput LFD Systems

A trend influencing the label free detection market is the notable shift toward automated, high-throughput LFD systems with integrated analytics. Companies are launching advanced SPR platforms that can analyze thousands of molecular interactions, complemented by automation tools that streamline assay set up and analysis. 

Additionally, existing BLI and SPR instruments are being upgraded to enhance performance. These technologies are adopted by academic and pharmaceutical labs to speed up key processes such as hit triage and epitope mapping, thereby shortening research and development timelines.

• In June 2025, Nicoya Lifesciences acquired British-based Applied Photophysics to enhance its biopharma technology offerings. The deal combined Nicoya’s Surface Plasmon Resonance (SPR) instruments with Applied's technologies, including circular dichroism (CD) and stopped-flow kinetics. This integration was intended to create a comprehensive platform for customers, providing data on protein function, structure, and stability from a single provider.

Regulatory Frameworks

• In the U.S., the FDA (U.S. Food and Drug Administration) mandates proper “Research Use Only” labeling and restricts diagnostic claims for RUO instruments (21 CFR 809.10(c)(2)(i)). LFD methods intended for regulated use must meet applicable GMP/Part 11 requirements, and be validated according to ICH guidelines.
• In the EU, the In Vitro Diagnostic Regulation (EU) 2017/746 (IVDR) raises evidence requirements for performance and clinical validation when LFD platforms are used in IVD workflows. RUO instruments must not make diagnostic claims.
• In China, the NMPA (National Medical Products Administration) Regulations oversee IVDs under the Supervision and Administration of Medical Devices (Decree 739). LFD systems designed for clinical or IVD use must adhere to NMPA registration and quality system requirements.
• In Japan, the Pharmaceuticals and Medical Devices Agency (PMDA) under the Ministry of Health, Labour and Welfare (MHLW) regulates IVD devices. Clinical use of LFD platforms requires proper device classification and pre-market review as per Japanese guidelines.
• In India, the Medical Device Rules, 2017, under the CDSCO, govern IVDs. RUO LFD tools must be labeled accordingly and must avoid clinical claims.
