Benefits of technology

[0007]One advantage of the present disclosure is the ability to induce motion in a composition of matter (referred to herein as an “artificial swimmer”) via changes of configuration of monomer units of a photoisomerizable polymer resulting from exposure to different wavelengths of light. Another advantage of the present disclosure is the ability of the artificial swimmer to “scavenge” metal ions from a solution using a chelating material as the artificial swimmer moves in various directions in the solution.

Problems solved by technology

However, there may be challenges associated with manufacturing such an artificial swimmer that is able to mimic the multiple-directional movement ability of a living organism.

Embodiment Construction

[0016]The present disclosure relates to photoisomerizing polymers (e.g., photoisomerizing azobenzene polymers) and compositions of matter that include the photoisomerizing polymers. In the present disclosure, a composition of matter that includes a particle (e.g., a silica particle) having a photoisomerizing polymer bonded to a first portion of the particle (e.g., a “tail” portion of the particle) and a chelating material bonded to a second portion of the particle (e.g., a “head” portion of the particle) is also referred to as an “artificial swimmer.” While the present disclosure refers to a silica particle (e.g., for addition of surface functionalities such as amine groups to the first portion of the particle), it will be appreciated that alternative particles may be utilized (e.g., for addition of alternative / additional surface functionalities to the first portion of the particle).

[0017]A potential use of the artificial swimmers of the present disclosure is “scavenging” of metal i...

Abstract

In an example, a process of forming a photoisomerizing azobenzene polymer includes chemically reacting an azobenzene material that includes at least two chlorocarbonyl functional groups with an amine to form a photoisomerizing azobenzene polymer. The photoisomerizing azobenzene polymer has a polymer chain that includes a first chlorocarbonyl group disposed at a first end of the polymer chain, a plurality of repeating azobenzene monomer units, and a second chlorocarbonyl group disposed at a second end of the polymer chain.

Description

I. CROSS REFERENCE TO RELATED APPLICATIONS[0001]This application is a divisional of co-pending U.S. patent application Ser. No. 14 / 730,804, filed Jun. 4, 2015 and entitled “PHOTOISOMERIZING POLYMERS”, which is herein incorporated by reference in its entirety.II. FIELD OF THE DISCLOSURE[0002]The present disclosure relates generally to photoisomerizing polymers.III. BACKGROUND[0003]Living organisms may swim with various movements from a contracting / expanding motion to the “wiggling” of a flagellum. An “artificial swimmer” that is able to mimic movements of a living organism may be useful in various contexts (e.g., drug delivery). However, there may be challenges associated with manufacturing such an artificial swimmer that is able to mimic the multiple-directional movement ability of a living organism.IV. SUMMARY OF THE DISCLOSURE[0004]According to an embodiment, a composition of matter is disclosed. The composition of matter includes a particle, a photoisomerizing polymer, and a chel...
