Area of Science:

  • Surgical Oncology
  • Molecular Imaging
  • Biomedical Engineering

Background:

  • Intraoperative tumor detection is crucial for surgical oncology, addressing unmet needs in cancer surgery.
  • Current methods rely on visual and tactile guidance, often supplemented by fluorescent contrast agents.
  • Limitations exist in precisely identifying tumor deposits, margins, and residual cancer.

Purpose of the Study:

  • To review novel strategies for developing and evaluating targeted dual-labeled molecular imaging agents.
  • To highlight the integration of fluorescent and nuclear imaging for enhanced intraoperative visualization.
  • To discuss the first-in-human application of this multimodality approach.

Main Methods:

Subviral Agents

Subviral agents are infectious entities that resemble viruses but lack one or more viral components, such as a capsid or essential replication machinery. These agents include viroids, prions, and satellites, each possessing distinct structural and functional characteristics that influence their mode of infection and replication.Viroids are the simplest subviral agents, consisting of circular, single-stranded RNA molecules without a protein coat. They exclusively infect plants, relying entirely...

Molecular and Ionic Solids

Crystalline solids are divided into four types: molecular, ionic, metallic, and covalent network based on the type of constituent units and their interparticle interactions.
Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
