Российские ученые предложили защищать импланты от бактерий наноиголками

Импланты используются в медицине для протезирования органов и суставов, заменителей сосудов, стимуляторов сердца и в косметологии. На поверхности силиконовых имплантов были нанесены наноиголки, которые предотвращают оседание бактерий и возникновение биопленок.

Диаметр иголок-столбиков составляет 500 или 700 нм, а микробы не могут разместиться на поверхности из-за расположения иголок на большом расстоянии друг от друга. Бактериям, которые все же попытаются осесть на иголки, оболочка натягивается и лопается, что приводит к их гибели.

Mr. Durov launched Telegram in late 2013 with his brother, Nikolai, just months before he was pushed out of VK, the Russian social-media platform he founded. Mr. Durov pitched his new app—funded with the proceeds from the VK sale—less as a business than as a way for people to send messages while avoiding government surveillance and censorship.

Telegram Q&A
Q: How does hottg.com work?
Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
