Cancer is a leading cause of death worldwide. Despite continuous efforts made to improve the shortcomings of the conventional approach, it remains formidable with high mortality. Contrary to the traditional approach, targeted therapies have emerged as a solution to fight against cancer. Nanoparticles containing targeted moiety have emerged as a cornerstone in cancer therapy. However, nano-cargo-based targeted therapy mainly involves biological molecules, such as nucleic acids, proteins, and immunomodulators, which target the mechanism involved in deranging cancer. Therefore, these biologically active molecules and their drug products require long-term stability inside and outside the body that can be enhanced using lyophilization and molecular recognition techniques. The paper attempts to provide a general overview of medication administration via nanoparticles for targeted cancer treatment and the effect of lyophilization on the stability of the formulation. This comprehensive review explores cutting-edge advancements in the fabrication of nanoparticles with an extensive range of methods and updated insights into lyophilization to improve the physicochemical characteristics of nanoparticles. The lyophilized process' development, scaling up, and transfer necessitate a number of NP formulation considerations as well as an optimized freeze-drying procedure to provide a high-quality cancer product. The review highlights the critical findings of in vitro and in vivo studies that have shown a strong and significant impact of lyophilization on the stability of nanoparticles, resulting in long shelf-life and potential biological response in cancer treatment. In summary, drug delivery using nanoparticles is a revolutionary strategy for treating cancer that requires stability and endurance for improved therapeutic results. The convergence of freeze drying in nano-based oncology can enhance the stability with a strong impact on cellular uptake by maintaining the intact concentration with less aggregation. This technique can have high potential for hybrid nanoparticles conjugated with biomolecules and improve the function of macromolecules, like proteins, antibodies, and nucleic acids, for cancer treatment.
