About CRS

CRS is the home for experts dedicated to delivery science, including delivery scientists, engineers, clinicians, and technical professionals. CRS members are creating the future of delivery science and technology through fundamental delivery research, development, regulatory science, and clinical translation. Research published in CRS journals and presented during the Annual Meeting & Exposition offers a breadth of scientific knowledge covering new technologies and science in the multi-disciplinary delivery field.

CRS 2021 Annual Meeting

Drug Delivery and Translational Research (DDTR)

Best Paper of the October 2020 Issue of DDTR: Local anesthesia enhanced with increasing high-frequency ultrasound intensity

Summary: The effect of local anesthetics, particularly those which are hydrophilic, such as tetrodotoxin (TTX), is impeded by tissue barriers that restrict access to individual nerve cells. Insonation has been used to disrupt vascular and cell membranes, which can facilitate transport of substances across biological barriers. Using an in vivo model of local anesthetic delivery, we investigated the effect of acoustic intensity on insonation-mediated delivery of local anesthetics to the peripheral nerve. We found that insonation at acoustic intensity greater than 0.5 W/cm2 was capable of enhancing TTX delivery to the peripheral nerve but not bupivacaine, a more hydrophobic local anesthetic. The finding here suggests that the effect of insonation on local drug delivery to the peripheral nerve depends on the hydrophilic/hydrophobic balance of the drug.

Inspirational Note from Dr. Jeff Hrkach and Prof. Bob Langer:  "From micro to nano: evolution and impact of drug delivery in treating disease"

"As editor-in-chief of DDTR, I am honored to bring such inspiration to the DD community. Many thanks to Bob and Jeff!

Editor-in-Chief Article

Drug Delivery and Translational Research is a journal published by CRS, providing a unique forum for the scientific publication of high-quality research that is exclusively focused on translational aspects of drug delivery. The journal is published 6 times a year and will be available online to CRS members as part of their annual dues.

Women In Science

Annual Meeting Women In Science Keynote 

Women in Science

The CRS WIS ran two very successful sessions during the virtual CRS2020 Annual Meeting. Prof. Alonso delivered a very inspirational talk about her career in science that prompted a lively Q&A session where participants could ask their questions live, triggering a collegial and warm atmosphere. We are super proud to announce that this year we had over 150 participants of different nationalities and seniorities, of which a fair amount were men, which we warmly welcome. This allowed a virtual mingling with women CRS past presidents, past Women in Science Award Winners, and peers.

Thank you all for making these sessions an outstanding success and especially thanks to Prof. Alonso for willingly sharing her legacy in science and her path to get there. We are looking forward to welcoming your ideas and experiences and to keep us all engaged. Please contact Ruth Schmid with any questions. We also hope to see you face-to-face in Montreal in 2021!
