Abstract

Conventional administration of drugs is limited by poor water solubility, low permeabil-ity, and mediocre targeting. Safe and effective delivery of drugs and therapeutic agents remains a challenge, especially for complex therapies, such as cancer treatment, pain management, heart fail-ure medication, among several others. Thus, delivery systems designed to improve the pharmaco-kinetics of loaded molecules, and allowing controlled release and target specific delivery, have re-ceived considerable attention in recent years. The last two decades have seen a growing interest among scientists and the pharmaceutical industry in mesoporous silica nanoparticles (MSNs) as drug delivery systems (DDS). This interest is due to the unique physicochemical properties, includ-ing high loading capacity, excellent biocompatibility, and easy functionalization. In this review, we discuss the current state of the art related to the preparation of drug‐loaded MSNs and their analy-sis, focusing on the newest advancements, and highlighting the advantages and disadvantages of different methods. Finally, we provide a concise outlook for the remaining challenges in the field.
