A Fully Integrated CMOS Bio-chip Aiming at Selective Assembly of Charged Nano-particles

摘要：

A fully integrated bio-chip targeting at electrical selective assembly of charged nano-particles is proposed and designed in SMIC 0.18μm CMOS mixed signal process. The proposed circuit integrates the electrode array,potentiostat circuit,and logics on a single chip,and provides a rail-to-rail range of assembly voltage,a potential resolution of 9 bit,and a maximal assembly current up to 0.46 mA,biased at a current of 1 μA. Meanwhile,a novel electrode-reuse scheme is also proposed to further simplify the architecture and save chip area as well,without degrading the functionalities. Experimental results from on-chip selective assembly of 50 nm poly-styrene nano-particles (PS) are included and discussed to verify the feasibility of the proposed circuits.
