Abstract
Compared with conventional chemotherapy and radiotherapy, targeted molecular therapy, e.g., antibody-drug conjugates or aptamer-drug conjugates, can specifically identify overexpressed natural receptors on the cancer cell, perform targeted release of anticancer drugs, and achieve targeted killing of tumor cells. However, many natural receptors are also expressed on non-cancer cells, thereby diverting the targeting molecules to healthy cells. By generating artificial cell surface receptors specific to diseased cells, aptamer-drug conjugates can identify these artificial receptors, improve therapeutic efficacy, and decrease the minimum effective dosage. In this study, we use high K+ and high H2O2 of the tumor microenvironment (TME) to produce polydopamine only on living cancer cell membrane. Owing to the significant reactivity of polydopamine with amino groups, e.g., the amino group of proteins, polydopamine can deposit on tumor cells and act as “artificial receptors” for targeted delivery of anticancer drugs with amino groups, in other words, amino-containing drugs and protein drugs. Polydopamine (PDA) generation catalyzed using G-quadruplex DNAzyme TME high K+ and H2O2 employed to produce PDA only on cancerous cells membrane PDA generated and deposited on cancerous cells and acted as artificial receptors PDA artificial receptors facilitated targeted delivery of drugs with amino groups

Abstract
Water-soluble deep cavitands embedded in a supported lipid bilayer are capable of anchoring ATRP initiator molecules for the in situ synthesis of primary amine-containing polymethacrylate patches at the water:membrane interface. These polymers can be derivatized in situ to incorporate fluorescent reporters, allow selective protein recognition, and can be applied to the immobilization of nonadherent cells at the bilayer interface.

Abstract
A novel targeting drug delivery system containing poly(styrene-alt-maleic anhydride)58-b-polystyrene130 (P(St-alt-MA)58-b-PSt130) as a copolymer backbone, N-acetyl glucosamine (NAG) as a targeting moiety was designed and synthesized. The NAG grafted copolymer (NAG-P(St-alt-MA)58-b-PSt130) was characterized by FTIR and (1)H NMR. The NAG-P(St-alt-MA)58-b-PSt130 nanoparticles exhibited spherical shapes with an average diameter about 56.27±0.43 nm, low critical micelle concentration of 0.028 mg/mL, negative zeta potential -41.46±0.99 mV, high drug loading 25.83±1.09% and encapsulation efficiency 69.69±3.98%. In vitro cell cytotoxicity was conducted to confirm the safety of the NAG-P(St-alt-MA)58-b-PSt130 nanoparticles. Confocal laser scanning microscopy (CLSM) and flow cytometry (FCM) results showed that the NAG targeting moiety enhanced the internalization and targeting ability of NAG-P(St-alt-MA)58-b-PSt130 nanoparticles. Anticancer activity toward MCF-7 cells and HT29 cells showed that DOX-loaded NAG-P(St-alt-MA)58-b-PSt130 nanoparticles exhibited a higher antitumor activity compared to DOX-loaded P(St-alt-MA)58-b-PSt130 nanoparticles, which could attribute to NAG receptor-mediated endocytosis. These results suggest that the biocompatible and non-toxic NAG-P(St-alt-MA)58-b-PSt130 nanoparticles may be used as an effective targeting drug delivery system for cancer therapy.

Abstract
Receptor-mediated endocytosis is a highly efficient mechanism for cellular uptake of membrane-impermeant ligands. Cells use this process to acquire nutrients, initiate signal transduction, promote development, regulate neurotransmission, and maintain homeostasis. Natural receptors that participate in receptor-mediated endocytosis are structurally diverse, ranging from large transmembrane proteins to small glycolipids embedded in the outer leaflet of cellular plasma membranes. Despite their vast structural differences, these receptors share common features of binding to extracellular ligands, clustering in dynamic membrane regions that pinch off to yield intracellular vesicles, and accumulation of receptor-ligand complexes in membrane-sealed endosomes. Receptors typically dissociate from ligands in endosomes and cycle back to the cell surface, whereas internalized ligands are usually delivered into lysosomes, where they are degraded, but some can escape and penetrate into the cytosol. Here, we review efforts to develop synthetic cell surface receptors, defined as nonnatural compounds, exemplified by mimics of cholesterol, that insert into plasma membranes, bind extracellular ligands including therapeutics, probes, and endogenous proteins, and engage endocytic membrane trafficking pathways. By mimicking natural mechanisms of receptor-mediated endocytosis, synthetic cell surface receptors have the potential to function as prosthetic molecules capable of seamlessly augmenting the endocytic uptake machinery of living mammalian cells.
