Single stranded siRNA complexation through non-electrostatic interactions

As double stranded, single stranded siRNA (ss-siRNA) has demonstrated gene silencing activity but still requires efficient carriers to reach its cytoplasmic target. To better understand the fundamental aspect driving the complexation of ss-siRNA with nanocarriers, the interactions between surfaces of various compositions across a ss-siRNA solution were investigated using the Surface Forces Apparatus. The results show that ss-siRNA can adsorb...
