Scientists from Saratov National Research State University (SSU) named after N. G. Chernyshevsky have developed a novel method for delivering anti-inflammatory drugs through hair follicles, potentially enhancing treatment efficacy while minimizing side effects, TASS reported with reference to the press service of the Ministry of Education and Science of the Russian Federation.
This advancement uses bioresorbable capsules—microscopic containers designed to dissolve in the body. These capsules penetrate hair follicles and release medication gradually.
Key to this research was the examination of the capsules’ behavior on the skin, including penetration depth, retention time, and drug release rate. The scientists employed non-invasive optical methods to assess these parameters without damaging the skin, although this approach is limited in depth of sensing. To address this challenge, they propose implementing optical illumination technology to enhance the «transparency» of the skin for better evaluation.
According to the press service, this innovative drug delivery technique has the potential to lower the required dosage and frequency of applications, while also reducing side effects by ensuring that the medication acts locally.
Earlier it was reported that Novosibirsk scientists have developed scintillating substances based on rare earth elements for the early diagnosis of cancer. The luminophores will allow doctors to detect traces of cancer foci at the cellular level for the targeted destruction of atypical cells.
