| Solid tumors form a permissive microenvironment with irregular features, including high pressured tumor interstitial fluid with acidic pH, co-adaptation of cancer cells with other cells like the immune system
cells, abnormal metabolism and anomalous overexpression of various pieces of molecular machinery. The
functional expressions of several oncomarkers in different solid tumors have led to the development of
targeted drug-delivery systems (DDSs). As a new class of DDSs, stimuli-responsive nanomedicines (SRNMs)
have been developed using advanced nanobiomaterials such as biopolymers that show excellent biocompatibility with low inherent immunogenicity. In this review, we aim to overview different types of SRNMs,
present deep insights into the stimuli-responsive biopolymers and discuss the most up-to-date progress in
the design and development of SRNMs used as advanced DDSs for targeted therapy of cancer |
