Improving cancer immunotherapies and biosensors with biomaterials

Bioactive Polymers

Research

Local infusion of immunotherapeutics (LIIT)

Many protein immunotherapeutics have limited efficacy for solid tumors due to tumor uptake barriers and poor pharmacokinetic profiles. We are using injectable infusion pumps with tunable release rates to for intratumoral implantation to improve the efficacy of immunotherapeutics.  

Intratumoral infusion pumps

Injectable hydrogels are being developed to control the release of protein therapeutics and immunotherapeutics to improve pharmacokinetic profiles for anti-cancer drugs and immunoengineer tumor microenvironments for improved pharmacodynamics. 

Immunoengineering solid tumors to enhance immunotherapies

Tumor microenvironments of solid tumors are commonly in a anti-inflammatory (cold) state that hinders the bioactivity of immunotherapeutics. We are exploring the use of injectable infusion pumps to alter the TME from anti- to pro-inflammatory (hot) to further enhance the efficacy of cancer immunotherapeutics. 

Polymers for targeting disease

To improve pharmacodynamics and pharmacokinetics of protein therapeutics, we are creating protein-polymer conjugates for applications in cancer immunotherapy and neutralization of viruses. 

Bioactive polymers

Polymers modified with bioactive molecules or proteins are being developed to target diseased tissue and viruses as well as improving biosensors. 

Polymeric coatings for biosensors

Methods to improve low-fouling properties and capture capacity of biosensors are being developed to detect specific molecules with complex media such as blood.
