Resistive switching in nano particle incorporated polymer and bio degradable films is now a fast growing field as it has memory applications. Further the conduction mechanisms involved that lead to switching are of great interest.

Giving a brief summary of the status of different emerging memory sytems, I shall describe our work and recent results on resistive switching in :

1. PMMA-Al doped ZnO nano particles,

2. PVA-reduced graphene oxide

3. Gelatin-Graphene Oxide,

4. Gelatin-CdTe quantum dots and

5. Gelatin-Silver nano particles.

Through systematic I-V characterization, the conduction mechanisms in these systems have been established.
