Transcript

Thank you so much David for the introduction and invitation. I would like to tell you a little bit about the work that we have been doing in our lab. I'm an engineer by training. By the way, I'm a chemical engineer who turned bio-engineer. So, I'm going to tell you about my perspective on solving an important problem in designing therapeutics. My l... Read More

Key Insights

• 🇨🇷 The cost of developing new drugs is currently very high, and innovative drug delivery technologies are needed to reduce costs and improve efficacy.
• 🚚 Biological barriers pose challenges in drug delivery, and understanding and overcoming these barriers is crucial for effective drug development.
• 😒 The use of ultrasound, ionic liquids, and innovative nanoparticle designs are being explored to enhance drug delivery across various biological barriers.
• 😪 Mimicking the properties and behaviors of natural cells, such as red blood cells and macrophages, can lead to novel drug delivery strategies.

Questions & Answers

Q: Why are biological barriers a challenge in drug delivery?

Biological barriers such as the skin, gastrointestinal tract, liver, and brain hinder the effective delivery of drugs to targeted areas. The body's natural defense mechanisms and complex principles make it difficult to control drug distribution.

Q: How can drug development costs be reduced?

The speaker suggests that developing innovative drug delivery technologies is key to reducing drug development costs. By overcoming biological barriers, drugs can be delivered more effectively, leading to lower production costs and shorter development times.

Q: What are some examples of drug delivery technologies being developed in the lab?

The speaker discusses the use of ultrasound to make the skin permeable and deliver drugs transdermally. They also describe the development of an ionic liquid called CAGE, which enhances the transport of proteins and peptides across the skin and gastrointestinal tract.

Q: How can the shape and physical properties of nanoparticles affect drug delivery?

The shape and physical properties of nanoparticles, such as flexibility and softness, can have a significant impact on their behavior in the body. For example, certain shapes can enhance cellular uptake, while soft particles can circulate in the bloodstream for longer periods, improving drug delivery efficiency.

Summary & Key Takeaways

• The speaker is an engineer-turned-bioengineer discussing the work done in their lab in the field of drug delivery and the importance of overcoming biological barriers.

• The high cost of drug development is a concern, with billions of dollars and several years required to develop a new drug.

• The speaker highlights the need to understand biological barriers and develop new tools and technologies to deliver drugs effectively and at a lower cost.
