Virus-like particles - capsides - are under intensive studies nowadays due to broad perspective for its applications as intracellular drug delivery agents. To ensure the effective treatment, the concentration of capsides in cell vicinity and inside the cell has to be high. One way to increase the local capsides concentration is grouping them all together, for instance, by attaching them to adjuvants - nanoparticles. These nanoparticles serve as „nano-lorry" which would deliver capsides inside the cell and reduce their residual concentration in the intracellular liquid. The present work explores possibility to use silicon dioxide nanoparticles as adjuvant to Hepatitis B capsides to create complexes „capsides - nanoparticles". Spectrophotometric measurements, electron and fluorescent microscopy demonstrated formation of the above complexes. In addition, vaccination of animals with the complexes-based vaccine resulted in twetve-time increase in antibody synthesis.
