Advanced Health Materials published the article “Multifunctional Biomedical Adhesives,” by Bruce Lee, Rupak Rajachar, Rattapol Pinnaratip, Saleh Akram Bhuiyan, and Kaylee Meyers (Biomed). This article is an invited review that described recent advances in designing multifunctional bioadhesives for various biomedical applications.
This review discusses strategies for engineering multifunctional biomedical adhesives, which involve two general approaches: passive and active design. Passive adhesives contain inherent structural elements that can carry out additional functions without external influences, whereas active adhesives are designed to respond to environmental changes. These adhesives exhibit new functionality such as antimicrobial properties, self‐healing ability, and the capacity to release drugs.

Tyo gave an oral presentation entitled “Optimizing of Two-Step Adhesive Coating for the Mitigation of Field Associated Infection in Cetacean Satellite Telemetry Tags,” a project directed by Rajachar.
Akram gave an oral presentation entitled “Controlling Redox Reaction of Conductive Smart Catechol Adhesive using Electrochemistry,” a project directed by Lee.
The meeting took place February 17-20, 2019.
Jingfeng Jiang is the principal investigator on a project that has received a $450,187 research and development grant from the National Institutes of Health, “Elastography-Based Analytics for Benign and Malignant Breast Disease.”
Ultrasound elastography is used to pinpoint possible tumors and differentiate malignant, cancerous growths from benign lesions throughout the body, including in the breast. “Cancer tissues are stiff, and aggressively change their surroundings,” says Jiang, an associate professor of biomedical engineering at Michigan Tech.
“Ultrasound elastography uses imaging to measure the stiffness of tissue. Depending on who does the reading, the accuracy can vary from 95 percent to 40 percent,” Jiang says. “Forty percent is very bad—you get 50 percent when you toss a coin. In part, the problem is that ultrasound elastography is a relatively new modality.”
Ultrasound elastography could be an excellent screening tool for women who have suspicious mammograms, but only if the results are properly interpreted. Jiang’s research team, along with Zhengfu Xu, assistant professor of mathematical sciences, will use their graphics processing unit (GPU) to perform advanced processing of raw ultrasound data so physicians can use that information in their clinical workflow. “Mainly, radiologists will use our software together with ultrasound elastography and ultrasound for diagnosis,” says Jiang. “Our goal is to greatly reduce the guesswork.”
Biomedical Engineering Associate Professor Jingfeng Jiang is the principal investigator on a project that has received a $450,187 research and development grant from the National Institutes of Health. Zhengfu Xu (Math), assistant professor of mathematical sciences, is co-pi. This is a three-year project.
Michigan Tech students interested in medicine, veterinary medicine and other health-related professions participated in the Health Professions Interview Workshop on Monday, April 9, 2018. The workshop was designed for students preparing for health-related graduate programs and admission interviews.
Thirteen pre-health students engaged in one-on-one personal interviews, Multiple Mini Interviews (MMI) and a large, team-building earthquake simulation.
“I really enjoyed the medical school mock interviews. I think MMIs are so unique to medical school interviews that most students don’t have any exposure to that kind of interaction,” said Rachel Wall, biological sciences student.
MMI interviews are used by many medical and health professions programs as part of the admissions process. An MMI is comprised of short, structured interview stations used to assess non-cognitive qualities and how applicants handle themselves in a particular situation. Some MMI stations involve role-playing situations where the interviewee is required to play a particular role and take an ethical stance in decision-making.
Wall continued, “Even the group activity portion is not something most people experience while being evaluated. I think those of us who participated in this will be much better prepared for our medical school interviews than our peers who haven’t had this type of exposure and practice.”
The biology department has hosted similar events in the past, but on a much smaller scale. This year, the pre-health department teamed up with Career Services to host a larger workshop for students of all majors with an interest in health professions.
More than a dozen volunteer interviewers, facilitators, actors and evaluators participated in the event—including faculty, students and staff from Pre-health, Biological Sciences, Biomedical Engineering, Kinesiology and Integrative Physiology, and Career Services. Central Michigan University’s Doctor of Physical Therapy Program also provided volunteers for the workshop.
The application and interview process for Health Professions Programs can be daunting, but this workshop, “is a part of the ongoing effort to grow and improve pre-health at Michigan Tech,” according to pre-health coordinator Nicole Seigneurie who spearheaded the workshop.
Elizabeth Scaife, biological sciences major, notes, “the Health Professions Interview Workshop was a wonderful experience full of challenging ethical questions, and a fun group activity that helped me find my strengths and weaknesses for future interviews for vet schools.”
