Abstract
The fabrication of novel and intelligent delivery systems that can effectively deliver therapeutics to the targeted site and release payload in enhanced/controlled manner is highly desired to overcome the multiple challenges in chemotherapy. The present article demonstrates the potential application of dual stimuli responsive nanogels as tumor microenvironment targeted drug delivery carrier. Disulfide cross-linked pH and redox responsive PEG-PDMAEMA nanogels were synthesized by atom transfer radical polymerization (ATRP). The nanogels were characterized by nuclear magnetic resonance (NMR) spectroscopy, Fourier transform infrared spectroscopy (FTIR), and X-ray diffraction (XRD). The PEG-PDMAEMA nanogels exhibited dual stimuli-responsive release of the encapsulated model anticancer drug (doxorubicin, DOX) due to the acidic pH-response of dimethyl amine group in PDMAEMA and reductive cleavage of the disulfide linkages. A relatively higher release of DOX was observed from the nanogels at pH 5.0 than at pH 7.4. DOX release was further accelerated in tumor simulated environment of pH 5.0 and 10 mM glutathione (GSH). Confocal microscopy images revealed that DOX-loaded PEG-PDMAEMA nanogels can rapidly internalize and effectively deliver the drug into the cells. The nanogels exhibited higher cytotoxicity in GSH-OEt pretreated HeLa cells than untreated cells. The dual stimuli responsive nanogels synthesized in this study exhibited many favorable traits, such as pH and redox dependent controlled release of drug, biodegradability, biocompatibility, and enhanced cytotoxicity, which endow them as a promising candidate for anticancer drug delivery.

Abstract
Zinc pthalocyanine (ZnPc) is a second-generation photodynamic therapy (PDT) sensitizer with sufficient PDT activity for squamous cell carcinoma (SCC). ZnPc is hydrophobic and insoluble in water, which creates hurdles in systemic administration and hence restricts its use in clinic. Here we have loaded ZnPc on chitosan/methoxy polyethylene glycol-polylactic acid (CPP) nanoparticles to form Z-CPP to enhance PDT efficacy. In vitro and in vivo studies were performed to see dark toxicity of the compounds ZnPc, CPP and Z-CPP. Then PDT was done and its growth inhibitory effect on SCC cells was evaluated. In addition, reactive oxygen species (ROS) formation and apoptosis of cancer cells following PDT were studied. The results showed that the tested compounds exhibit no dark toxicity and the effect of PDT was significantly better with Z-CPP when compared to free ZnPc (P < .05). Photoactivation of Z-CPP led to a dose-dependent growth inhibition of cancer cells of >50% at 1 μM to >80% at 10 μM concentration. Also Z-CPP-treated cells had highest number of apoptotic cells and produced more ROS compared to free ZnPc-treated cells (P < .05). Hence, this study suggests that Z-CPP is a suitable pharmaceutical compound to increase PDT efficacy.
