Nanofluidics

The Nanofluidics Subgroup works mainly on researching the sensing property of nanofluidic crystal and achieving highly sensitive bio/chemical molecules detection on chip. The members of the Nanofluidics Subgroup include Pan Zhang (Post-doc), Yechang Guo (Ph.D. candidate), Peiyue Li (Ph.D. student) and Shaofeng Wang (Master student). By now, they have achieved:

(1) Nanofluidic crystal chips

(a)-(e) Nanofluidic crystal chips’ size and SEM images, (f) Chip’s structure, (g) Chip’s stability, (h) Chip’s application on ionic detection.

(2)Achieved highly sensitive detection of bio/chemical molecules on chip by using funnel nanochannel with nanoparticle trapped at the tip.

(a) Schematic view of the chip, (b) Fabrication process, (c)~(d) Typical SEM image, (f) Confocal image of funnel nanochannel with trapped nanoparticle, (g) I-V curves of the funnel nanochannel with and without nanoparticle, (h) Typical I-V curves with different kinds of nanoparticles loaded into funnel nanochannels, (i) Nanoparticle loading
