HNT-liposome-coated surfaces enhance MCF7 and COLO 205 cell capture. (a) MCF7 breast cancer cells adhered to a smooth microtube coated with ES-PEG L-DXR. Scale bar = 100 μm. (b) MCF7 cells adhered to an HNT-coated microtube with ES-PEG L-DXR. Scale bar = 100 μm. (c) Number of MCF7 cells adhered to smooth and HNT-coated microtubes per 100,000 μm². (d) Number of COLO 205 cells adhered to smooth and HNT-coated microtubes per 100,000 μm². *𝑃<0.01. **𝑃<0.001.
