Benefits of technology

This patented method allows for efficient production of small molecules with high purity without generating harmful chemical waste or requiring expensive equipment such as solvents. These methods use commonly available materials like formaldehydes instead of complex organic compounds. Additionally, these techniques allow for precise control over how many different types of polymer chains form during reaction (molality) and how they interact together through interactions within each chain's structure.

Problems solved by technology

This patented technical problem addressed in this patents relating to making nano particles called plasmon hydrocilsensors (PNHC' s). These particles were found to attach themselves to other materials like metal surfaces when they interacted chemistryally. They could potentially replace existing drugs used in cancer treatment due to their ability to bind specifically to certain targets while being less harmful than traditional medications. Additionally, these particles had specific functions depending upon how well they work under physiological conditions.
