Abstract
Over the last decade, nanotechnology has widely addressed many nanomaterials in the biomedical area with an opportunity to achieve better-targeted delivery, effective treatment, and an improved safety profile. Nanocarriers have the potential property to protect the active molecule during drug delivery. Depending on the employing nanosystem, the delivery of drugs and genes has enhanced the bioavailability of the molecule at the disease site and exercised an excellent control of the molecule release. Herein, the chapter discusses various advanced nanomaterials designed to develop better nanocarrier systems used to face different diseases such as cancer, heart failure, and malaria. Furthermore, we demonstrate the great attention to the promising role of nanocarriers in ease diagnostic and biodistribution for successful clinical cancer therapy.

Abstract
In order to improve the therapeutic effect, prolong the action time and reduce the side effects of the first generation thrombolytic drug urokinase (UK), a novel UK/multi-walled carbon nanotubes (MWCNTs)-chitosan (CS)-arginine-glycine-aspartic acid (Arg-Gly-Asp) (RGD) drug delivery system was synthesized by chemical bonding/non covalent bond modification/ultrasonic dispersion. The results showed that the diameter of the UK/MWCNTs-CS-RGD drug delivery system was about 30-40 nm, there was a layer of UK was attached to the surface of the tube wall, and the distribution was relatively uniform. The average encapsulation efficiency was 83.10%, and the average drug loading was 12.81%. Interestingly, it also had a certain sustained-release effect, and its release law was best fitted by first-order kinetic equation. Moreover, the accelerated and long-term stability test results show that it had good stability. Compared with free UK, UK/MWCNTs-CS-RGD had thrombolytic effect in vitro. In addition, MTT experiment showed that the prepared MWCNTs-CS-RGD nanomaterials had good biocompatibility. A rabbit model of carotid artery thrombosis was used to conduct targeted thrombolysis experiments in vivo. Compared with free UK, UK/MWCNTs-CS-RGD could be enriched in the thrombosis site to achieve thrombus targeting. UK/MWCNTs-CS-RGD drug delivery system was expected to become an effective thrombolytic drug for targeted therapy of thrombosis.

Abstract
Functional ligands and polymers have frequently been used to yield target-specific bio-nanoconjugates. Herein, we provide a systematic insight into the effect of the chain length of poly(oligo (ethylene glycol) methyl ether acrylate) (POEGMEA) containing polyethylene glycol on the colloidal stability and antibody-conjugation efficiency of nanoparticles. We employed Reversible Addition-Fragmentation Chain Transfer (RAFT) to design diblock copolymers composed of 7 monoacryloxyethyl phosphate (MAEP) units and 6, 13, 35, or 55 OEGMEA units. We find that when the POEGMEA chain is short, the polymer cannot effectively stabilize the nanoparticles, and when the POEGMEA chain is long, the nanoparticles cannot be efficiently conjugated to antibody. In other words, the majority of the carboxylic groups in larger POEGMEA chains are inaccessible to further chemical modification. We demonstrate that the polymer containing 13 OEGMEA units can effectively bind up to 64% of the antibody molecules, while the binding efficiency drops to 50% and 0% for the polymer containing 35 and 55 OEGMEA units. Moreover, flow cytometry assay statistically shows that about 9% of the coupled antibody retained its activity to recognize B220 biomarkers on the B cells. This work suggests a library of stabile, specific, and bioactive lanthanide-doped nanoconjugates for flow cytometry and mass cytometry application.

Abstract
PURPOSE The aim of this study was to investigate two clinically approved plasma volume expanders (dextran 70 and voluven) as macromolecular MRI-chemical exchange saturation transfer (CEST) contrast agents to assess tumor vascular properties. METHODS CEST contrast efficiency of both molecules (6% w/v) was measured in vitro at various irradiation saturation powers (1-6 μT for 5 s) and pH values (range, 5.5-7.9) and the exchange rate of hydroxyl protons was calculated. In vivo studies in a murine adenocarcinoma model (n = 4 mice for each contrast agent) upon i.v. injection provided CEST-derived perfusion tumor properties that were compared with those obtained with a gadolinium-based blood-pool agent (Gd-AAZTA-Madec). RESULTS In vitro measurements showed a marked CEST contrast dependency to pH, with higher CEST contrast at lower pH values for both molecules. The measured prototropic exchange rates confirmed a base-catalyzed exchange rate that was faster for dextran 70 in comparison to voluven. Both molecules showed a similar CEST contrast increase (ΔST% > 3%) in the tumor tissue up to 30 min postinjection, with heterogeneous accumulation. In tumors receiving both CEST and T1 -weighted agents, a voxel-by-voxel analysis indicated moderate spatial correlation of perfusion properties between voluven/dextran 70 and Gd-AAZTA-Madec, suggesting different distribution patterns according to their molecular size. CONCLUSIONS The obtained results showed that both voluven and dextran 70 can be exploited as MRI-CEST contrast agents for evaluating tumor enhancement properties. Their increased accumulation in tumors and prolonged contrast enhancement promote their use as blood-pool MRI-CEST agents to examine tumor vascularization.

Abstract
Cross-linked derivatives of acylated branched polyethyleneimine containing 2-isopropyl-2-oxazoline units were investigated in chloroform and aqueous solutions using methods of molecular hydrodynamics, static and dynamic light scattering, and turbidity. The studied samples differed by the cross-linker content. The solubility of the polyethyleneimines studied worsened with the increasing mole fraction of the cross-linker. Cross-linked polyethyleneimines were characterized by small dimensions in comparison with linear analogs; the increase in the cross-linker content leads to a growth of intramolecular density. At low temperatures, the aqueous solutions of investigated samples were molecularly dispersed, and the large aggregates were formed due to the dehydration of oxazoline units and the formation of intermolecular hydrogen bonds. For the cross-linked polyethyleneimines, the phase separation temperatures were lower than that for linear and star-shaped poly-2-isopropyl-2-oxazolines. The low critical solution temperature of the solutions of studied polymers decreased with the increasing cross-linker mole fraction. The time of establishment of the constant characteristics of the studied solutions after the jump-like change in temperature reaches 3000 s, which is at least two times longer than for linear polymers.

Abstract
Magnetic resonance imaging (MRI) is the most powerful tool for deep penetration and high-quality 3D imaging of tissues with anatomical details. However, the sensitivity of the MRI technique is not as good as that of the radioactive or optical imaging methods. Carbon-based nanomaterials have attracted significant attention in biomaterial research in recent decades due to their unique physical properties, versatile functionalization chemistry, as well as excellent biological compatibility. Researchers have employed various carbon nano-allotropes to develop hybrid MRI contrast agents for improved sensitivity. This review summarizes the new research progresses in carbon-based hybrid MRI contrast agents, especially those reported in the past five years. The review will only focus on T2-weighted MRI agents and will be categorized by the different carbon allotrope types and magnetic components. Considering the strong trend in recent bio-nanotechnology research towards multifunctional diagnosis and therapy, carbon-based MRI contrast agents integrated with other imaging modalities or therapeutic functions are also covered.

Abstract
In this study, we report the synthesis, characterization and utilization of 99mTc-labelled polyethylenimine-entrapped gold nanoparticles (99mTc-Au-PENPs) for dual mode single-photon emission computed tomography/computed tomography (SPECT/CT) imaging applications. Polyethylenimine (PEI) was selected as a platform to conjugate with diethylene triamine pentacetate acid (DTPA) and polyethylene glycol monomethyl ether to synthesize Au PENPs, followed by acetylation or hydroxylation modification of the remaining PEI surface amine groups and radiolabelling of 99mTc. The generated multifunctional 99mTc-Au-PENPs with different surface groups (acetyl or hydroxyl) were characterized via different methods. The Au PENPs before 99mTc labelling are colloidally stable, haemocompatibility and noncytotoxic at an Au concentration up to 100 μM. The 99mTc-labelled Au PENPs exhibit high radiochemical purity, good stability and SPECT/CT imaging performance of different organs and lymph node. The designed strategy to use the radionuclide labelling technique and PEI-facilitated versatile nanoplatform may be extended to develop various novel nanoprobes for precision imaging applications.

Abstract
Considering the chemical exchange between gadolinium centers and water protons, nanosystems comprising gadolinium conjugated with high specific area nanocarriers might serve as more robust clinical tools for diagnosis and imaging-guided therapy. Herein, a pH-responsive nanosystem containing graphene oxide conjugated with a folic acid- and gadolinium-labeled dendrimer (FA-GCGLD) to boost its T1 contrast ability was developed, and doxorubicin (DOX) and colchicine (COLC) were efficiently loaded onto this nanosystem (FA-GCGLD-DOX/COLC). This nanosystem showed a prominent T1 contrast with an ultrahigh relaxivity of up to 11.6 mM-1 s-1 and pH-responsive drug release behavior. HepG2 cells treated with FA-GCGLD-DOX/COLC were efficiently inhibited, and the cell contrast was enhanced. In vivo, the tumor accumulation of FA-GCGLD-DOX/COLC significantly increased, thereby facilitating the systemic delivery of particles and exerting tumor growth inhibition and an enhanced tumor contrast effect. Moreover, compared to free drugs, FA-GCGLD-DOX/COLC effectively decreased the drug resistance of the tumor, thereby improving the cancer chemotherapeutic efficacy. In addition, injecting rats with FA-GCGLD afforded excellent magnetic resonance angiography (MRA) images with high-resolution vascular structures because of the long blood circulation time of FA-GCGLD. Thus, this study provides a powerful tool for diverse applications in the biomedical field, including accurate diagnosis and chemotherapy of tumors and the detection of cardiovascular diseases.

Here, we report the design and synthesis of Au NPs entrapped within polyethylene glycol (PEG)-modified branched polyethyleneimine (PEI) with varying the initial Au salt/PEI molar ratios and with the remaining PEI surface amines being acetylated for blood pool, lung tumor and lymph node CT imaging. The formed unacetylated and acetylated PEGylated PEI-entrapped Au NPs (Au PENPs) were characterized via different methods. We show that the PEGylated PEI is an effective template to entrap Au NPs having a uniform size ranging from 1.7nm to 4.4nm depending on the Au salt/PEI molar ratio. After optimization of the composition-dependent X-ray attenuation effect, we then selected {(Au0)100-PEI·NHAc-mPEG} NPs for biological testing and show that the particles have good cytocompatibility in the given concentration range and can be used as a contrast agent for effective CT imaging of the blood pool of rats, lung cancer model of nude mice and lymph node of rabbits after intravenous injection. For each application, the injected dosage of the particles was optimized. In addition, the {(Au0)100-PEI·NHAc-mPEG} NPs could be excreted out of the body with time. Our results indicate that the formed Au PENPs with an appropriate composition and dosage hold a great promise to be used for CT imaging of various biosystems.

Abstract
Cancer diagnosis and treatment represent an urgent medical need given the rising cancer incidence over the past few decades. Cancer theranostics, namely, the combination of diagnostics and therapeutics within a single agent, are being developed using various anticancer drug-, siRNA-, or inorganic materials-loaded nanocarriers. Herein, we demonstrate a strategy of encapsulating quantum dots, superparamagnetic Fe3O4 nanocrystals, and doxorubicin (DOX) into biodegradable poly(d,l-lactic-co-glycolic acid) (PLGA) polymeric nanocomposites using the double emulsion solvent evaporation method, followed by coupling to the amine group of polyethyleneimine premodified with polyethylene glycol-folic acid (PEI-PEG-FA [PPF]) segments and adsorption of vascular endothelial growth factor (VEGF)-targeted small hairpin RNA (shRNA). VEGF is important for tumor growth, progression, and metastasis. These drug-loaded luminescent/magnetic PLGA-based hybrid nanocomposites (LDM-PLGA/PPF/VEGF shRNA) were fabricated for tumor-specific targeting, drug/gene delivery, and cancer imaging. The data showed that LDM-PLGA/PPF/VEGF shRNA nanocomposites can codeliver DOX and VEGF shRNA into tumor cells and effectively suppress VEGF expression, exhibiting remarkable synergistic antitumor effects both in vitro and in vivo. The cell viability waŝ14% when treated with LDM-PLGA/PPF/VEGF shRNA nanocomposites ([DOX] =25 μg/mL), and in vivo tumor growth data showed that the tumor volume decreased by 81% compared with the saline group at 21 days postinjection. Magnetic resonance and fluorescence imaging data revealed that the luminescent/magnetic hybrid nanocomposites may also be used as an efficient nanoprobe for enhanced T2-weighted magnetic resonance and fluorescence imaging in vitro and in vivo. The present work validates the great potential of the developed multifunctional LDM-PLGA/PPF/VEGF shRNA nanocomposites as effective theranostic agents through the codelivery of drugs/genes and dual-modality imaging in cancer treatment.

Abstract
Gene therapy has arisen as a pioneering technique to treat diseases by direct employment of nucleic acids as medicine. The major historical problem is to develop efficient and safe systems for the delivery of therapeutic genes into the target cells. Carbon nanotubes (CNTs) have demonstrated considerable promise as delivery vectors due to their (i) high aspect ratio and (ii) capacity to translocate through plasma membranes, known as the nanoneedle effect. To leverage these advantages, close attention needs to be paid to the physicochemical characteristics of the CNTs used. CNTs with different diameters (thinner and thicker) were treated by chemical oxidation to produce shorter fragments. Rigid (thick) and flexible (thin) CNTs, and their shortened versions, were coated with polyallylamine (ppAA) by plasma-enhanced chemical vapor deposition. The ppAA coating leads to a positively charged CNT surface that is able to electrostatically bind the green fluorescent protein plasmid reporter. This study shows how rigidity and length can affect their (i) behavior in biological media, (ii) ability to transfect in vitro, and (iii) biodistribution in vivo. This study also generates a set of basic design rules for the development of more efficient CNT-based gene-delivery vectors.

Abstract
Development of versatile nanomaterials combining diagnostic and therapeutic functionalities within one single nanoplatform is extremely important for tumor theranostics. In this work, the authors report the synthesis of a gold nanostar (Au NS)-based theranostic platform stabilized with cyclic arginine-glycine-aspartic (Arg-Gly-Asp, RGD) peptide-modified amine-terminated generation 3 poly(amidoamine) dendrimers. The formed RGD-modified dendrimer-stabilized Au NSs (RGD-Au DSNSs) are used as a gene delivery vector to complex small interfering RNA (siRNA) for computed tomography (CT) imaging, thermal imaging, photothermal therapy (PTT), and gene therapy of tumors. The results show that the RGD-Au DSNSs are able to compact vascular endothelial growth factor siRNA and specifically deliver siRNA to cancer cells overexpressing αv β3 integrin. Under near-infrared laser irradiation, the viability of cancer cells is only 20.2% after incubation with the RGD-Au DSNS/siRNA polyplexes, which is much lower than that of cells after single PTT or gene therapy treatment. Furthermore, in vivo results show that the RGD-Au DSNS/siRNA polyplexes enable tumor CT imaging, thermal imaging, PTT, and gene therapy after intratumoral injection. These results indicate that the developed multifunctional nanoconstruct is a promising platform for tumor imaging and combinational PTT and gene therapy.

Abstract
The polymerase chain reaction (PCR) is considered an excellent technique and is widely used in both molecular biology research and various clinical applications. However, the presence of byproducts and low output are limitations generally associated with this technique. Recently, the use of nanoparticles (NPs) has been shown to be very effective at enhancing PCR. Although mechanisms underlying this process have been suggested, most of them are mainly based on PCR results under certain situations without abundant systematic experimental strategy. In order to overcome these challenges, we synthesized a series of polyethylene glycol (PEG)-modified polyethylenimine (PEI)-entrapped gold nanoparticles (PEG-Au PENPs), each having different gold contents. The role of the synthesized NPs in improving the PCR technique was then systematically evaluated using the error-prone two-round PCR and GC-rich PCR (74% GC content). Our results suggest a possible mechanism of PCR enhancement. In the error-prone two-round PCR system, the improvement of the specificity and efficiency of the technique using the PEG-Au PENPs mainly depends on surface-charge-mediated electrostatic interactions. In the GC-rich PCR system, thermal conduction may be the dominant factor. These important findings offer a breakthrough in understanding the mechanisms involved in improving PCR amplification, as well as in the application of nanomaterials in different fields, particularly in biology and medicine.

Abstract
Attachment of polyethylene glycol (PEG) can prolong blood circulation of biological molecules, a useful trait for a vascular imaging agent. Here, we present a route for modifying octabutoxy naphthalocyanine (ONc) with PEG, via axial conjugation following ONc chelation with Sn(IV) chloride (Sn-ONc). Tin chelation caused ONc absorbance to shift from 860 to 930 nm. Hydroxy terminated PEG was treated with sodium and then was axially attached to the tin, generating PEG-Sn-ONc. Unlike ONc or Sn-ONc, PEG-Sn-ONc was soluble in methanol. ONc and PEG-Sn-ONc were dissolved in polysorbate solutions and administered to mice intravenously. PEG-Sn-ONc demonstrated substantially longer blood circulation time than ONc, with a 4 times longer half-life and a nearly 10 times greater area under the curve. PEG-Sn-ONc gave rise to photoacoustic contrast and could be used for noninvasive brain vessel imaging even 24 h following injection. This work demonstrates that nonmetallic naphthalocyanines can be chelated with tin, and be axially modified with PEG for enhanced circulation times for long-term vascular imaging with photoacoustic tomography.

Abstract
Development of new long-circulating contrast agents for computed tomography (CT) imaging of different biological systems still remains a great challenge. Here, we report the design and synthesis of branched polyethyleneimine (PEI)-stabilized gold nanoparticles (Au PSNPs) modified with polyethylene glycol (PEG) for blood pool, lymph node, and tumor CT imaging. In this study, thiolated PEI was first synthesized and used as a stabilizing agent to form AuNPs. The formed Au PSNPs were then grafted with PEG monomethyl ether via PEI amine-enabled conjugation chemistry, followed by acetylation of the remaining PEI surface amines. The formed PEGylated Au PSNPs were characterized via different methods. We show that the PEGylated Au PSNPs with an Au core size of 5.1 nm have a relatively long half-decay time (7.8 h), and display a better X-ray attenuation property than conventionally used iodine-based CT contrast agents (e.g., Omnipaque), and are hemocompatible and cytocompatible in a given concentration range. These properties of the Au PSNPs afford their uses as a contrast agent for effective CT imaging of the blood pool and major organs of rats, lymph node of rabbits, and the xenografted tumor model of mice. Importantly, the PEGylated Au PSNPs could be excreted out of the body with time and also showed excellent in vivo stability. These findings suggest that the formed PEGylated Au PSNPs may be used as a promising contrast agent for CT imaging of different biological systems.

Abstract
Carbon-based nanomaterials have attracted much interest during the last decade for biomedical applications. Multimodal imaging probes based on carbon nano-onions (CNOs) have emerged as a platform for bioimaging because of their cell-penetration properties and minimal systemic toxicity. Here, we describe the covalent functionalization of CNOs with fluorescein and folic acid moieties for both imaging and targeting cancer cells. The modified CNOs display high brightness and photostability in aqueous solutions and their selective and rapid uptake in two different cancer cell lines without significant cytotoxicity was demonstrated. The localization of the functionalized CNOs in late-endosomes cell compartments was revealed by a correlative approach with confocal and transmission electron microscopy. Understanding the biological response of functionalized CNOs with the capability to target cancer cells and localize the nanoparticles in the cellular environment, will pave the way for the development of a new generation of imaging probes for future biomedical studies.

Abstract
We report the use of multifunctional dendrimer-entrapped gold nanoparticles (Au DENPs) loaded with gadolinium (Gd) chelator/Gd(III) complexes and surface-modified with thiolated cyclo(Arg-Gly-Asp-Phe-Lys(mpa)) (RGD) peptide for targeted dual-mode computed tomography (CT)/magnetic resonance (MR) imaging of small tumors. In this study, amine-terminated generation 5 poly(amidoamine) dendrimers were used as a nanoplatform to be covalently modified with Gd chelator, RGD via a polyethylene glycol (PEG) spacer, and PEG monomethyl ether. Then the multifunctional dendrimers were used as templates to entrap gold nanoparticles, followed by chelating Gd(III) ions and acetylation of the remaining dendrimer terminal amines. The thus-formed multifunctional Au DENPs (in short, Gd-Au DENPs-RGD) were characterized via different techniques. We show that the multifunctional Au DENPs with a Au core size of 3.8 nm are water-dispersible, stable under different pH (5-8) and temperature conditions (4-50 °C), and noncytotoxic at a Au concentration up to 100 μM. With the displayed X-ray attenuation property and the r1 relaxivity (2.643 mM(-1) s(-1)), the developed Gd-Au DENPs-RGD are able to be used as a dual-mode nanoprobe for targeted CT/MR imaging of an αvβ3 integrin-overexpressing xenografted small tumor model in vivo via RGD-mediated active targeting pathway. The developed multifunctional Gd-Au DENPs-RGD may be used as a promising dual-mode nanoprobe for targeted CT/MR imaging of different types of αvβ3 integrin-overexpressing cancer.

Abstract
We report the use of arginine-glycine-aspartic (Arg-Gly-Asp, RGD) peptide-modified dendrimer-entrapped gold nanoparticles (Au DENPs) for highly efficient and specific gene delivery to stem cells. In this study, generation 5 poly(amidoamine) dendrimers modified with RGD via a poly(ethylene glycol) (PEG) spacer and with PEG monomethyl ether were used as templates to entrap gold nanoparticles (AuNPs). The native and the RGD-modified PEGylated dendrimers and the respective well characterized Au DENPs were used as vectors to transfect human mesenchymal stem cells (hMSCs) with plasmid DNA (pDNA) carrying both the enhanced green fluorescent protein and the luciferase (pEGFPLuc) reporter genes, as well as pDNA encoding the human bone morphogenetic protein-2 (hBMP-2) gene. We show that all vectors are capable of transfecting the hMSCs with both pDNAs. Gene transfection using pEGFPLuc was demonstrated by quantitative Luc activity assay and qualitative evaluation by fluorescence microscopy. For the transfection with hBMP-2, the gene delivery efficiency was evaluated by monitoring the hBMP-2 concentration and the level of osteogenic differentiation of the hMSCs via alkaline phosphatase activity, osteocalcin secretion, calcium deposition, and von Kossa staining assays. Our results reveal that the stem cell gene delivery efficiency is largely dependent on the composition and the surface functionality of the dendrimer-based vectors. The coexistence of RGD and AuNPs rendered the designed dendrimeric vector with specific stem cell binding ability likely via binding of integrin receptor on the cell surface and improved three-dimensional conformation of dendrimers, which is beneficial for highly efficient and specific stem cell gene delivery applications.

Abstract
Application of anticoagulants remains the primary strategy for prevention and treatment of thrombosis. However, high rate of bleeding complications limits their use. The peptide anticoagulant bivalirudin has been reported to exhibit a lower rate of bleeding complications than heparin, and it also has the advantage of not causing thrombocytopenia, which is a problem with heparin. Nonetheless, hemorrhage is the most common complication of bivalirudin therapy, and there is no effective antidote. Here we use a thrombus-binding peptide, CR(NMe)EKA, to accomplish selective delivery of the bivalirudin-carrying micellar nanocarrier to sites of thrombosis. Bivalirudin and CR(NMe)EKA, each with a PEG-lipid tail, spontaneously assembled into 30 nm micelles, which almost completely retained the anticoagulant activity of bivalirudin. The micellar formulations exhibited high stability both in vitro and in vivo. In a thromboplastin-induced mouse thrombosis model, the targeted micelles accumulated in lung thrombi 10-fold more than nontargeted micelles. Moreover, the micellar formulation significantly prolonged the half-life and thereby increased the bioavailability of bivalirudin. The micellar bivalirudin had significantly higher anticoagulant activity than free bivalirudin in both the lung thrombosis model and a ferric chloride-induced carotid artery thrombosis model. The specific targeting of thrombi demonstrated here makes it possible to increase the efficacy of bivalirudin as an anticoagulant. Alternatively, the dose could be reduced without loss of efficacy to lower the systemic exposure and improve safety.

Abstract
The synthesis and characterization of gold nanoparticles (AuNPs) entrapped within polyethylene glycol (PEG)-modified polyethylenimine (PEI) for blood pool and tumor computed tomography (CT) imaging are reported. In this approach, partially PEGylated PEI was used as a template for AuNP synthesis, followed by acetylating the PEI remaining surface amines. The synthesized PEGylated PEI-entrapped AuNPs (Au PENPs) were characterized via different methods. Our results reveal that the synthesized Au PENPs can be tuned to have an Au core size in a range of 1.9-4.6 nm and to be water-soluble, stable, and noncytotoxic in a studied concentration range. With a demonstrated better X-ray attenuation property than that of clinically used iodinated small molecular contrast agent (e.g., Omnipaque) and the prolonged half-decay time (11.2 h in rat) confirmed by pharmacokinetics studies, the developed PEGylated Au PENPs enabled efficient and enhanced blood pool CT imaging with imaging time up to 75 min. Likewise, thanks to the enhanced permeability and retention effect, the PEGylated Au PENPs were also able to be used as a contrast agent for effective CT imaging of a tumor model. With the proven organ biocompatibility by histological studies, the designed PEGylated Au PENPs may hold great promise to be used as contrast agents for CT imaging of a variety of biological systems. The significance of this study is that rather than the use of dendrimers as templates, cost-effective branched polymers (e.g., PEI) can be used as templates to generate functionalized AuNPs for CT imaging applications.

Abstract
Currently used small molecular magnetic resonance (MR) imaging contrast agents (CAs) in clinics have relatively short half-lives, which has limited the acquisition of high-resolution organ and angiographic images. Therefore, development of a facile strategy for the synthesis of long-circulating CAs with the transforming potential for MR imaging still remains a great challenge. Here we communicate the design and synthesis of PEGylated polyethylenimine (PEI) and its application as enhanced T1 CA for the long-circulating blood pool as well as efficient organ and tumor imaging. In this study, PEI was covalently grafted with gadolinium (Gd(III)) chelator and mPEG-NHS, followed by acetylation of the remaining amines to improve biocompatibility and prolong circulation time. With the relatively long circulation time (3.8 h), the formed multifunctional PEI (PEI.NHAc-DTPA(Gd(III))-mPEG) can be used as an enhanced T1 CA for blood pool and major organ imaging, and could be cleared from the body 96 h post administration through the urinary system. Importantly, the PEI.NHAc-DTPA(Gd(III))-mPEG complexes displayed a strong T1 contrast effect for tumor imaging through the enhanced permeation and retention effect. These findings suggest that the synthesized PEI.NHAc-DTPA(Gd(III))-mPEG may be used as a promising CA for T1 MR imaging of various biological systems.
