HETEROGENEOUS MICROPARTICLES, AND SYSTEMS AND METHODS OF MAKING AND USE THEREOF - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240033310 titled 'HETEROGENEOUS MICROPARTICLES, AND SYSTEMS AND METHODS OF MAKING AND USE THEREOF

Simplified Explanation

The patent application describes a method for creating microparticles with a shell, payload, and cap using additive manufacturing techniques. The shell has a core and an orifice that is sealed by the cap. When triggered, the orifice is exposed, allowing the payload to be released from the core.

  • The microparticles are formed using additive manufacturing methods, such as patterning of photomaterials or particle beams.
  • The orifice of each microparticle is sealed by a cap, preventing the release of the payload.
  • When a triggering event occurs, the orifice is exposed, allowing the payload to be released through the exposed portion.
  • The technology can be used in various applications, including controlled delivery of drugs, chemicals, or biological agents, self-healing or self-lubricating materials, and failure prevention or mitigation.

Potential Applications:

  • Controlled delivery of drugs, chemicals, or biological agents.
  • Self-healing or self-lubricating materials.
  • Failure prevention or mitigation.

Problems Solved:

  • Controlled release of payloads from microparticles.
  • Efficient and precise manufacturing of microparticles with shells, payloads, and caps.

Benefits:

  • Improved control over the release of drugs, chemicals, or biological agents.
  • Enhanced functionality of self-healing or self-lubricating materials.
  • Increased reliability and safety in failure prevention or mitigation.


Original Abstract Submitted

a plurality of heterogeneous microparticles can be provided, each having a shell, a payload, and a cap. the shell can define a core and an orifice in fluid communication with the core. the payload can be disposed within the core. the cap can be coupled to the shell so as to seal the orifice. the shell and cap of the microparticles can be formed by an additive manufacturing method, for example, by patterning of photomaterials using electromagnetic radiation or a particle beam. when subjected to a triggering event, at least a portion of each orifice can be exposed from the respective cap so as to release, through the exposed orifice portion, the corresponding payload from the core of the shell. the microparticles can be used in various applications, such as controlled delivery of drugs, chemicals, or biological agents, self-healing or self-lubricating materials, and failure prevention or mitigation.
