The Protein Engineering and Molecular Design Lab began July 2005. Broadly, our lab is focused on engineering macromolecules. The long-term goal of our lab research is to be able to predictably design or engineer artificial therapeutics, biocatalysts, scaffolds and cells. We seek to provide biologically inspired solutions to address the challenges of human disorder treatment and medicine, sustainable energy and environmental remediation.

Effect of Divalent Metal Cations on the Conformation, Elastic Behavior, and Controlled Release of a Photocrosslinked Protein Engineered Hydrogel
This research was conducted by Jin Kim Montclare, Professor of Chemical and Biomolecular Engineering; and former students Yao Wang, a recent Ph. D. graduate, and Xiaole Wang, a former M.S. student.
Protein hydrogels are versatile 3-dimensional macromolecular structures with an astonishing variety of potential applications, many of them in medicine, including tissue engineering and wound healing. Because of their hydrophilic properties and internal architecture, these compounds can even trap and deliver drugs directly to targets, opening up a host of potential applications involving safe delivery of cytotoxic compounds that are standard treatment for cancer and other diseases.
To have such “Swiss Army Knife” capabilities, these typically soft materials must be imbued with properties conferring static and dynamic mechanical strength that enables them to carry a molecular payload and know when to release it.
Taking up this challenge, Montclare and her former students built upon recent work developing a photo-crosslinkable triblock copolymer protein hydrogel called CEC-D, a compound with limited viscoelastic mechanical and moderate sustained release properties. In the new work they explored the potential of transition metal cations (positively charged ions) to enhance the mechanical properties of CED-D, including its ability to encapsulate and release the small molecule curcumin, known for its anti-inflammatory properties.
In the paper, “Effect of Divalent Metal Cations on the Conformation, Elastic Behavior, and Controlled Release of a Photocrosslinked Protein Engineered Hydrogel,” published in the ACS publication Applied Bio Materials, the investigators found that the hydrogels coordinated with divalent metal ions such as Zn2+, Cu2+, and Ni2+ demonstrated control over the encapsulation and release of curcumin, a discovery suggesting that cation-tuned hydrogels constitute a promising drug delivery platform with tunable physicochemical properties.
“Depending on the metal, we can control the structure, mechanical stiffness and small molecule delivery of the hydrogel,” said Montclare. “This has important implications for drug delivery and this knowledge can be used to tailor vehicles to deliver specific therapeutics. For example, we can tailor these materials to fabricate wound dressings that improve healing by triggering drug release in the presence of metals.”

This research was conducted by Jin Kim Montclare, Professor of Chemical and Biomolecular Engineering; and former students Yao Wang, a recent Ph. D. graduate, and Xiaole Wang, a former M.S. student.
Protein hydrogels, 3-dimensional macromolecular structures that do not dissolve in water (in spite of being hydrophilic), can hold large quantities of aqueous solutions due to the network formed from chemical or physical crosslinking. Partly because of this they have many medical applications including tissue engineering, wound healing and drug delivery.
These materials can be synthesized by crosslinking polymers chemically via covalent bonds, or physically via non-covalent interactions, or a mixture of both. One way of doing this is through photo-initiated crosslinking, wherein chemically inert groups become photo-reactive once exposed to certain wavelengths of light.
“The advantage of employing photochemical reactive groups over traditional chemical reagents is that they give the user spatiotemporal control over polymerization,“ said Montclare. “In other words, the biopolymers bearing the photocrosslinkers can be generated and crosslinked at some later step under various conditions to achieve control over encapsulation and release of therapeutic agents.”
In this research, the team designed a macromolecular triblock polymer comprising two different self-assembling domains derived from elastin protein (E) and coiled-coil protein (C), that can be photopolymerized due to an a NHS-diazirine (D) crosslinker to produce a CEC-D hydrogel.
In the work, “Free-Standing Photocrosslinked Protein Polymer Hydrogels for Sustained Drug Release,” in Biomacromolecules, a publication of the American Chemical Society, the investigators determined the best photocrosslinker concentration and exposure time necessary to create this independent hydrogel.
The researchers found that, overall, CEC-D hydrogel exhibits comparable characteristics, including stability, drug release profile, and elastic behavior to other hydrogels.
Because it can be used for drug delivery with high encapsulation and a low but significant release of curcumin, CEC-D has been proven to be capable of a sustained release of a given drug over a week's time.
