About

Hongshen Ma is a pioneering researcher at the intersection of microfluidics, cell biology, and biomedical engineering. His work focuses on developing innovative platforms for rare cell analysis, particularly in immunocytochemistry and single-cell technologies. Ma’s most notable contribution is the invention of lossless immunocytochemistry using photo-polymerized hydrogel thin-films, a breakthrough method that preserves cellular antigens and enables high-fidelity phenotyping of extremely small cell populations—down to just a few hundred cells. This technique overcomes a critical limitation of standard immunofluorescence microscopy, which often fails with samples containing fewer than 10,000 cells. By encapsulating cells in a hydrogel matrix, Ma’s approach achieves near-complete retention of cellular material, eliminating the significant cell loss that plagues conventional protocols. With 4 citations, this foundational work is gaining traction in the rare cell analysis community. Ma’s broader research portfolio spans microfluidic devices for circulating tumor cell isolation, point-of-care diagnostics, and organ-on-a-chip systems. His achievements include multiple patents and collaborations with clinical partners to translate lab innovations into practical tools for cancer diagnosis and personalized medicine.
