We report the development of a small molecule-based barcoding platform for pooled screening of nanoparticle delivery. Using aryl halide-based tags (halocodes), we achieve high-sensitivity detection via gas chromatography coupled with mass spectrometry or electron capture. This enables barcoding and tracking of nanoparticles with minimal halocode concentrations and without altering their physicochemical properties.

Nanoparticles have the potential to improve disease treatment and diagnosis due to their ability to incorporate drugs, alter pharmacokinetics, and enable tissue targeting. While considerable effort is placed on developing spherical lipid-based nanocarriers, recent evidence suggests that high aspect ratio lipid nanocarriers can exhibit enhanced disease site targeting and altered cellular interactions. However, the assembly of lipid-based nanoparticles into non-spherical morphologies has typically required incorporating additional agents such as synthetic polymers, proteins, lipid-polymer conjugates, or detergents.

Article Synopsis
  • The Black Sea, a semi-enclosed inland sea, features anoxic deep waters and is home to various marine mammals, including local subspecies of dolphins and harbour porpoises.
  • Research teams from Bulgaria, Georgia, Romania, Türkiye, and Ukraine deployed F-PODs between September 2020 and October 2022 to study the acoustic activity of harbour porpoises, uncovering strong seasonal and diel patterns across different regions.
  • Findings indicated that porpoises in the southeastern Black Sea showed increased acoustic activity during the spring, aligning with the seasonal migration of anchovies, while western and northwestern porpoises demonstrated distinct bimodal and daylight activity patterns linked to the feeding habits of sprat.
