- (1) target medications to specific organ systems to increase bioavailability
- (2) extend the release of medications so that frequent administration is not necessary
Tissue engineering is needed to develop vehicles to deliver therapeutic molecules (such as repurposed small-molecule drugs, monoclonal antibodies, and oligonucleotides) to the desired area.

Role of Tissue Engineering in COVID-19 and Future Viral Outbreaks

Roles of In Vitro Models for COVID-19
In vitro models:
- (1) allow for better characterization and understanding of the host-pathogen interface and mechanisms of infection of SARS-CoV-2
- (2) serve as a platform for high-throughput screening of potential therapeutics for SARS-CoV-2
Accruate in vitro modeling is important to identify biomarkers that can serve as diagnostic and therapeutic targets.

Roles of Drug Delivery System Development for COVID-19

Biomaterials act as:
- (1) Particle-based platforms: biomaterials serve as the drug delivery vehicle for vaccines as well as the adjuvant to enhance immune system response. 
- (2) scaffold systems: pore size, profile of released recruitment signals, scaffolds, etc can potentially be used to concentrate antigen-presenting cells to vaccine components
