Article Abstract

Aptamers have been widely researched and applied in nanomedicine due to their programmable, activatable, and switchable properties. However, there are few reviews on aptamer-controlled stimuli-responsive drug delivery. This article highlights the mechanisms and advantages of aptamers in the construction of stimuli-responsive drug delivery systems. We summarize the assembly/reconfiguration mechanisms of aptamers in controlled release systems. The assembly and drug release strategies of drug delivery systems are illustrated. Specifically, we focus on the binding mechanisms to the target and the factors that induce/inhibit the binding to the stimuli, such as strand, pH, light, and temperature. The applications of aptamer-based stimuli-responsive drug release are elaborated. The challenges are discussed, and the future directions are proposed.

The lower gastrointestinal (GI) tract is affected by a range of diseases, including colorectal cancer and inflammatory bowel disease, among others. Effective treatment of these conditions requires drug delivery systems (DDSs) capable of precise targeting. While pH- and enzyme-sensitive DDSs are the most used, they often suffer from premature drug release and target specificity, limiting their efficacy.

Polysaccharide copolymers Conjuates have surfaced as a versatile foundation in the development of advanced smart drug delivery systems, owing to their inherent biocompatibility, biodegradability, and capacity for chemical modification. This review brings into focus the recent advances in co-polymeric drug delivery systems based on naturally occurring polysaccharides like chitosan, alginate, dextran, hyaluronic acid, pullulan, guar gum, xanthan gum, agarose, gellan gum, and starch. Their structural malleability and functionalization capabilities are emphasized to engineer therapeutic payload stability, bioavailability, and controlled release.

Phospholipid-derived nanocarriers represent a versatile and chemically customizable class of drug delivery systems that self-assemble into bilayered vesicles due to their intrinsic amphiphilicity. These systems can encapsulate both hydrophilic and hydrophobic drugs through non-covalent interactions and manipulation of lipid phase behavior. This review examines the molecular and supramolecular principles underlying the formation, stability, and functional performance of key phospholipid-based nanocarriers-including liposomes, transferosomes, ethosomes, invasomes, phytosomes, pharmacosomes, and virosomes.

Stimuli-responsive hydrogels have gained significant attention in wound care due to their ability to adapt to dynamic physiological conditions, making them promising candidates for facilitating chronic wound healing. These hydrogels can respond to both internal and external environmental stimuli such as temperature, pH, reactive oxygen species (ROS), glucose levels, MMP, mechanical forces, magnetism, and ultrasound, enabling precise, on-demand therapeutic interventions through controlled drug release. This responsiveness is governed by reversible changes in their polymer network structure caused by interactions with external stimuli.
