copper-64 was produced in large scales and high specific activities in late 1990s’ using compact cyclotrons based by 64ni(p,n)64cu reaction and many radiopharmaceuticals developed since then by various groups based on interesting physicochemical and nuclear properties of the radionuclide. the unique emission of beta particles as well as positron particles offers a spectacular real therapeutic/d...

Molecular imaging has often provided tantalizing potential for tracking theranostic agents during in vivo studies. Each in vivo imaging modality has its limitations, which has impeded the application of molecular imaging towards theranostics research. For example, Magnetic Resonance Spectroscopy (MRS) has been used to detect drug delivery with great molecular specificity due to the unique MR fr...

Due to their tunable surface plasmon and photothermal effects, gold nanorods (AuNRs) have proved to be promising in a wide range of biomedical applications such as imaging, hyperthermia therapy and drug delivery. All these applications can be remotely controlled by near infrared (NIR) light which can penetrate deep into human tissues with minimal lateral invasion. AuNRs thus hold the potential ...

Theranostic delivery systems are nanostructures that combine the modality of therapy and diagnostic imaging. Polymeric micro- and nanobubbles, spherical vesicles containing a gas core, have been proposed as new theranostic carriers for MRI-guided therapy. In this study, chitosan nanobubbles were purposely tuned for the co-delivery of prednisolone phosphate and a Gd(III) complex, as therapeutic ...

BACKGROUND Theranostic perfluorocarbon nanoprobes have recently attracted attention due to their fascinating versatility in integrating diagnostics and therapeutics into a single system. Furthermore, although 17β-estradiol (E2) is a potential anti-hypertrophic drug, it has severe non-specific adverse effects in various organs. Therefore, we have developed cardiomyocyte-targeted theranostic nano...

To achieve accurate tumor location and highly efficient cancer therapy effect, the properties of cancer theranostic agents should be optimized and enhanced. In this work, ultra-small Nd doped NaDyF4 were firstly reported as novel contrast agents for near-infrared second window downconversion luminescence (NIR II DCL) and magnetic resonance imaging. Based on the optimization strategy, gallic aci...

Background: The emergence of two-dimensional MXenes has spurred their versatile applications in broad fields, but the exploring of novel MXene-based family members and their potential applications in theranostic nanomedicine (concurrent diagnostic imaging and therapy) have been rarely explored. In this work, we report the construction of a novel superparamagnetic MXene-based theranostic nanopla...

Targeted theranostics is increasingly attractive in the cancer field to reduce off-target effects and provide rapid diagnosis. Neurotensin (NT) and its derivatives target neuortensin receptor 1 (NTS1) which has strong, selective, aberrant expression in certain tumour cells. This commentary briefly describes the advantages of targeting using the NT/NTS1 pairing and discusses a recent article on ...

Nowadays cancer remains one of the main causes of death in the world. Current diagnostic techniques need to be improved to provide earlier diagnosis and treatment. Traditional therapy approaches to cancer are limited by lack of specificity and systemic toxicity. In this scenario nanomaterials could be good allies to give more specific cancer treatment effectively reducing undesired side effects...

A multifunctional gold nanorod (AuNR) complex is described with potential utility for theranostic anticancer treatment. The AuNR was functionalized with cyclodextrin for encapsulation of doxorubicin, with folic acid for targeting, and with a photo-responsive dextran-azo compound for intracellular controlled drug release. The interaction of a AuNR complex with HeLa cells was facilitated via a fo...
