Hybrid (2D/3D) Dosimetry of Radiolabeled Gold Nanoparticles for Sentinel Lymph Node Detection in Patients with Breast Cancer. [PDF]

Contrast Media Mol Imaging, 2020
Previously, we reported the preparation and preclinical studies of 99mTc‐labeled gold nanoparticles‐mannose (99mTc‐AuNP‐mannose) with potential for sentinel lymph node (SLN) detection by using nuclear medicine procedures. This study aimed to evaluate the biokinetics and hybrid (2D/3D) dosimetry of 99mTc‐AuNP‐mannose in five patients with breast cancer ...

^99mTc-CXCR4-L for Imaging of the Chemokine-4 Receptor Associated with Brain Tumor Invasiveness: Biokinetics, Radiation Dosimetry, and Proof of Concept in Humans. [PDF]

Contrast Media Mol Imaging, 2020
Overexpression of the chemokine‐4 receptor (CXCR4) in brain tumors is associated with high cancer cell invasiveness. Recently, we reported the preclinical evaluation of 99mTc‐CXCR4‐L (cyclo‐D‐Tyr‐D‐[NMe]Orn[EDDA‐99mTc‐6‐hydrazinylnicotinyl]‐Arg‐NaI‐Gly) as a SPECT radioligand capable of specifically detecting the CXCR4 protein.

¹⁷⁷Lu-DOTA-HYNIC-Lys(Nal)-Urea-Glu: Biokinetics, Dosimetry, and Evaluation in Patients with Advanced Prostate Cancer. [PDF]

Contrast Media Mol Imaging, 2018
SPECT/CT images in patients have demonstrated the ability of [99mTc]Tc‐EDDA/HYNIC‐Lys(Nal)‐Urea‐Glu ([99mTc]Tc‐iPSMA) to detect tumors and metastases of prostate cancer. Considering that theranostics combines the potential of therapeutic and diagnostic radionuclides in the same molecular probe, the aim of this research was to estimate the biokinetics ...

Study of the Optical Properties of Functionalized Gold Nanoparticles in Different Tissues and Their Correlation with the Temperature Increase

Journal of Nanomaterials, Volume 2017, Issue 1, 2017., 2017
Mie theory explains the interaction of light with a gold nanoparticle (AuNP) through the absorption (Cabs), scattering (Csca), and extinction (Cext) cross sections. These parameters have been calculated in the case of AuNPs dispersed in homogeneous media, but not for specific tissues.

Preparation and Characterization of a Tumor‐Targeting Dual‐Image System Based on Iron Oxide Nanoparticles Functionalized with Folic Acid and Rhodamine

Journal of Nanomaterials, Volume 2017, Issue 1, 2017., 2017
Cancer is one of the diseases with most deaths worldwide, around 8.2 million annually. For this reason, several treatments and diagnostic tools have been investigated and developed over the past decades. Among them, a dual‐image system has been developed to achieve and enhance the detection of cancer, which has not been done with systems currently ...

Antibacterial Efficacy of Gold and Silver Nanoparticles Functionalized with the Ubiquicidin (29–41) Antimicrobial Peptide

Journal of Nanomaterials, Volume 2017, Issue 1, 2017., 2017
Recent studies have demonstrated that drug antimicrobial activity is enhanced when metallic nanoparticles are used as an inorganic support, obtaining synergic effects against microorganisms. The cationic antimicrobial peptide ubiquicidin 29–41 (UBI) has demonstrated high affinity and sensitivity towards fungal and bacterial infections.

177Lu‐Dendrimer Conjugated to Folate and Bombesin with Gold Nanoparticles in the Dendritic Cavity: A Potential Theranostic Radiopharmaceutical

Journal of Nanomaterials, Volume 2016, Issue 1, 2016., 2016
177Lu‐labeled nanoparticles conjugated to biomolecules have been proposed as a new class of theranostic radiopharmaceuticals. The aim of this research was to synthesize 177Lu‐dendrimer(PAMAM‐G4)‐folate‐bombesin with gold nanoparticles (AuNPs) in the dendritic cavity and to evaluate the radiopharmaceutical potential for targeted radiotherapy and the ...
