Core–shell structured gold nanoparticles as carrier for ¹⁶⁶Dy/¹⁶⁶Ho in vivo generator

Background: Radionuclide therapy (RNT) has become a very important treatment modality for cancer nowadays. Comparing with other cancer treatment options, sufficient efficacy could be achieved in RNT with lower toxicity. β⁻ emitters are frequently used in RNT due to the long tissue penetration depth of the β⁻ particles....

Radionuclide generator-based production of therapeutic 177Lu from its long-lived isomer 177mLu

Background In this work, a lutetium-177 (177Lu) production method based on the separation of nuclear isomers, 177mLu & 177Lu, is reported. The 177mLu-177Lu separation is performed by combining the use of DOTA & DOTA-labelled peptide (DOTATATE) and liquid-liquid extraction. Methods The 177mLu cations were complexed with DOTA &...

Separation of nuclear isomers for cancer therapeutic radionuclides based on nuclear decay after-effects

177Lu has sprung as a promising radionuclide for targeted therapy. The low soft tissue penetration of its β− emission results in very efficient energy deposition in small-size tumours. Because of this, 177Lu is used in the treatment of neuroendocrine tumours and is also clinically approved for prostate cancer therapy. In this work, we report a...

A Critical Review of Alpha Radionuclide Therapy: How to Deal with Recoiling Daughters?

This review presents an overview of the successes and challenges currently faced in alpha radionuclide therapy. Alpha particles have an advantage in killing tumour cells as compared to beta or gamma radiation due to their short penetration depth and high linear energy transfer (LET). Touching briefly on the clinical successes of radionuclides...
