Problem Statement

  • RNA interference (RNAi) involves introducing a short dsRNA into cells to silence gene expression.
  • The RNA-induced silencing complex (RISC) recognizes and binds to target mRNA, inhibiting translation or protein expression.
  • Essential in gene-based therapeutics for diseases like cancer, microbial infections, neurological disorders, immune-mediated diseases, and genetic disorders.
  • Challenges include safe, efficient, and economical delivery of siRNA molecules due to their anionic nature, low stability, and short half-life.
  • Need for improved calcium lactate nanostructure-based transfection reagent for effective gene silencing and therapeutic applications.

Technology
