  • NANOGEL PARTICLES HAVING DUAL FUNCTIONALITY AND TEMPERATURE RESPONSIVENESS FOR PARTICLE CLUSTERING IN NUCLEIC ACID SEQUENCING SYSTEMS
    Publication number: 20240117426
    Abstract: In some examples, novel nanogel particles are described having dual functionality, temperature responsiveness and pH responsiveness. For nucleic acid sequencing, amplification primers are grafted to nanogel particles to form primer-grafted nanogel particles, and the primer-grafted nanogel particles are captured onto surfaces within a flow cell. Within flow cells such as used in SBS nucleic acid sequencing, each primer-grafted nanogel particle functions as a nano-well in the flow cell, thus eliminating the need for nano-wells in some examples.

  • Ethylene glycol esters as photoactive agents
    Publication number: 20070191329
    Abstract: New compounds useful in photodynamic therapy are of the formula and their 1,4-diene isomers and the metallated and/or labeled and/or conjugated forms thereof wherein each R1 is independently alkyl(1-6C); each n is independently an integer of 0-6; and R2 is vinyl or a derivative form thereof.
