i want to make gold nanoconjugate with Unani drug. Kindly help me.

dear Wale,

yes, of course. The protocol was published in an Open Access Journal, and there is another detail on the langth of the biomolecule spacer that you would have to consider for optimal conjugation efficiency.

Here the two references:

This is very briliant, Dr. stephan, will you be kind enough to share the protocol of how you synthesis this in the Lab with me? thank you

Dear Navin Jain,

it is an Animation based on experimental results (Open access Publication: Barchanski, A. ; Sajti, C. L. ; Sehring, C. ; Petersen, S. ; BARCIKOWSKI, S.: Design of Bi-functional Bioconjugated Gold Nanoparticles by Pulsed Laser Ablation with Minimized Degradation. In: JLMN - Journal of Laser Micro/Nanoengineering 6 (2011), Nr. 2, S. 124–130)

The animation software was run by Martin Langhammer (http://www.youtube.com/user/FRONTSICHT).

First of all, congrats for such a nice approach.

Is this study also includes in silico experiments??

Can you share the details of the software used for preparing the video???

Thanks in advance

Navin Jain

Often, only one function is not enough. Multivalent gold nanoparticle conjugates combine two functions. Here: the cationic peptide helps translocating the cell membrane and the oligonucleotide allows binding to gene sequence inside the nucleus.
