An intracellular delivery vehicle of which surface is covered by a positive charge, an intracellular delivery complex in which a component or compound desired is loaded in the intracellular delivery vehicle, a temperature-sensitive probe comprising the intracellular delivery complex, and a method for measuring the intracellular temperature by the temperature-sensitive probe are disclosed. The intracellular delivery vehicle is useful on account of its capability of easily delivering the component or compound desired inside the cell without inhibiting cell proliferation.

This present invention relates to a polymer of -glutamyl transpeptidase catalyzing hydrolysis-induced charge reversal. The polymer comprises a -glutamyl transpeptidase-responsive element represented by Formula (I). When the polymer is used as drug carrier for anticancer drug, it can have a long circulation time in the blood, and can realize a charge reversal from negatively charged or the neutral to positively charged around the tumor blood vessel region, so that the positively charged polymer effectively penetrates deep into the tumor tissue, fast entering into the tumor cells, and greatly improves the therapeutic effect of the drug on the tumor. This overcomes the problems of slow diffusion of traditional polymer drug carriers in tumors and weak interaction with tumor cells, and has great significance in the field of anticancer treatment in the medical field.
