The premise is such that we have two independently fabricated su8 fluidic structures, we want to integrate them by bonding them together to make them functional. Any insights, standard protocols, or even brief thoughts on better ways to achieve SU-8 to SU-8 bonding by using any methods, chemical, physical, etc will be highly appreciated?.

Dear Bhushan Kharbikar,
I did once during my post doc year in James Watt Nano Fabrication Centre, University of Glasgow.
1. Clean the surface that you want to attach / integrate - perhaps with ultrasonic desiccator.
2. Expose the desired surface with O2 plasma in vacuum chamber, in my case approximately 30 sec - I never exposed longer than that as I remembered.
3. Using the tweezer, attach / integrate the exposure surface.
4. Let's the clock ticking for around 30 - 45 min, then it's now ready to utilize.
I hope this helps. All the best & Cheerio
