  • Publication number: 20220062370
    Abstract: A liquid ink composition includes a liquid phase and particles suspended in the liquid phase, the particles containing a target pharmaceutical or biological agent. The biological activity of the target pharmaceutical or biological agent is preserved upon suspension of the particles in the liquid phase. The liquid phase is capable of solidifying via a solidification process.

  • Patent number: 7705135
    Abstract: Pectins having a combination of unexpectedly high molecular weights and low degrees of methylation have been isolated from Aloe vera plants, are superior gel pectins for forming calcium cross-lined gels. Such pectins can be obtained by extracting homogenized Aloe Vera plants or portions thereof. These pectins can be used to prepare pharmaceutical compositions comprising pharmacological agents for application to animals and humans, so as to provide controlled release of the pharmacological agent.

    Assignee: Nanotherapeutics, Inc.
    Inventors: Yawei Ni, Kenneth M. Yates, Ryszard Zarzycki
  • Patent number: 7691986
    Abstract: Pectins having a combination of unexpectedly high molecular weights and low degrees of methylation have been isolated. These high molecular weight, low degree of methylation pectins form gels at unexpectedly low concentrations. Such pectins can be obtained by extracting homogenized Aloe Vera plants or portions thereof. These pectins can be used to prepare pharmaceutical compositions comprising pharmacological agents encapsulated in a pectin gel, for application to animals and humans so as to provide controlled release of the pharmacological agent.

  • Patent number: 5929051
    Abstract: Pectins from gel and rind cell wall fibers of Aloe vera are extracted, isolated and identified. Two classes of Aloe pectin are obtained: the high-molecular-weight (HMW) pectin and the low-molecular-weight (LMW) pectin. Aloe pectins have a low methoxyl (LM) content. Aloe pectins form gel in the presence of calcium, and they, especially, the HMW pectin, form monovalent cation-based gels at low temperature, which revert back to solution when brought to room temperature. The HMW Aloe pectin-calcium gel is used for controlled release. The monovalent cation-based gel is used as a matrix for storing pharmacological substances and also for antigen and antibody precipitation reaction.
