A molecular logic gate is a basic element and plays a key role in molecular computing. Herein, we have developed a label-free and enzyme-free three-input visual majority logic gate which is realized for the first time according to DNA hybridization only, without DNA replacement and enzyme catalysis. Furthermore, a one-vote veto function was integrated into the DNA-based majority logic gate, in ...

We present a technique to improve embedding capacity of Image using digital logic in this paper. We have applied digital logic operations on two equal halves of an image row to derive the hidden information. We have also compared the change in image using proposed technique and digital logic gate technique. Change in Image using proposed technique is half or more than that of logic gate techniq...
