Tumour development is overwhelmingly affected through the dealings of cancer cells with their environment which eventually conclude whether the primary tumour is eliminated, metastasizes or creates dormant micro metastases. The TME may perhaps shape therapeutic responses as well as resistance. Some inimitable features of TME, for example vascular abnormalities, hypoxia, acidic pH and glutathione (GSH) are comparative to normal tissue. Several types of cells, together with tumour cells, macrophages, immune and fibroblast cells are nourished by flawed blood vessels in the solid tumour. To dispense anticancer agents to tumour sites nanovehicles can be competent carts. For augmented therapeutic efficacy, TME is the key for designing of nanoparticles (NPs). In this review, we will discuss the TME and summarize the current advancement in several nano-formulations for cancer therapy, with an extraordinary stress on TME-responsive ones. Scheme 1 highlights several TME modulation tactics with positive cancer therapeut...
