    Bias the + input to 1/2 Vcc - you might want to select a rail-to-rail type as you've just halved the voltage headroom.

    I used lm358 as single supply amplifier for amplifying the output from a alcohol sensor, I found that output is saturating on 3.5v, How can i inprove this..?.

    This has to change. We can not guess what voltage you have provided for the LM358. We can not guess how you have arranged the circuits. We choose not to drag the information out of you over the course of several days. Give the information required to receive a useful answer NOW.
