Light Chaser Biotech

Light Chaser Biotech, operating as OptoSeeker, is a life sciences company developing advanced tools for cellular analysis. Founded in September 2023, the firm leverages its proprietary Optoelectronic Tweezers (OET) technology, which combines light and electricity to precisely manipulate microscopic objects. This platform enables the non-invasive, precise handling and analysis of single cells, which is critical for development in biopharmaceuticals, cell and gene therapy (CGT), and synthetic biology.

The company's product portfolio includes an Optoelectronic Tweezer System and a Digital Microfluidic Platform designed for applications such as cell line development, antibody discovery, and diagnostics. OptoSeeker's technology aims to improve upon traditional methods by offering faster and more accurate results. For example, its collaboration on an electroosmotic-driven digital optofluidics (e-DOF) platform resulted in a label-free protein detection test that reduces assay times to 15 minutes, a significant improvement over the hours required for conventional ELISA tests.

Based in Shenzhen, China, OptoSeeker has been recognized for its technological contributions, receiving a grant from the Shenzhen Major Science and Technology Special Fund in June 2025. This funding supports the company's research and development, intellectual property portfolio expansion, and the commercialization of its OET-based solutions. The company serves clients in research and pharmaceuticals, providing tools for applications in optogenetics, chemical analysis, and micro/nano manipulation.
