ক্রায়োসার্জারি হলো এমন একটি চিকিৎসা পদ্ধতি যার মাধ্যমে অত্যন্ত নিম্ন তাপমাত্রায় শরীরের অস্বাভাবিক বা রোগাক্রান্ত কোষগুলোকে ধ্বংস করা যায়। গ্রিক শব্দ ‘ক্রায়ো (বরফের মতো ঠাণ্ডা)’ এবং ‘সার্জারি (হাতের কাজ)’ শব্দ দুটি হতে ক্রায়োসার্জারি শব্দটি এসেছে। ঐতিহাসিকভাবেই বেশ কিছু রোগের চিকিৎসার জন্য ক্রায়োসার্জারিকে ব্যবহার করা হতো যাদের মধ্যে বিভিন্ন ধরনের বিপজ্জনক চর্ম সংক্রান্ত সমস্যাও রয়েছে। যে তাপমাত্রায় বরফ জমাট বাঁধে দেহকোষে তার চাইতেও নিম্ন তাপমাত্রার ধ্বংসাত্মক শক্তির সুবিধাকে গ্রহণ করে ক্রায়োসার্জারি কাজ করে। এতে নিম্ন তাপমাত্রায় দেহকোষের অভ্যন্তরস্থ বরফ ক্রিস্টালগুলোর বিশেষ আকার বা বিন্যাসকে ছিন্ন করে দূরে সরিয়ে দেয়া যায়। ক্রায়োসার্জারির ক্ষেত্রে সাধারণত পৃথক পৃথকভাবে তরল নাইট্রোজেন, কার্বন ডাইঅক্সাইডের তুষার, আর্গন এবং সমন্বিতভাবে ডাইমিথাইল ইথার ও প্রোপেন এর মিশ্রণ ব্যবহার করা হয়। এদের কোনো কোনোটি −41°C তাপমাত্রার উদ্ভব ঘটায়।

Cryosurgery (cryotherapy) is the use of extreme cold in surgery to destroy abnormal or diseased tissue. The term comes from the Greek words cryo (κρύο) ("icy cold") and surgery (cheirourgiki – χειρουργική) meaning "hand work" or "handiwork". Cryosurgery has been historically used to treat a number of diseases and disorders, especially a variety of benign and malignant skin conditions. Method Liquid nitrogen Cryogun used to spray liquid nitrogen A common method of freezing lesions is using liquid nitrogen as the cooling solution. This −196 °C (−321 °F) cold liquid may be sprayed on the diseased tissue, circulated through a tube called a cryoprobe, or simply dabbed on with a cotton or foam swab. Carbon dioxide Carbon dioxide is also available as a spray and is used to treat a variety of benign spots. Less frequently, doctors use carbon dioxide "snow" formed into a cylinder or mixed with acetone to form a slush that is applied directly to the treated tissue. Argon Recent advances in technology have allowed for the use of argon gas to drive ice formation using a principle known as the Joule-Thomson effect. This gives physicians excellent control of the ice, and minimizing complications using ultra-thin 17 gauge cryoneedles. Dimethyl ether – propane A mixture of dimethyl ether and propane is used in some preparations such as Dr. Scholl's Freeze Away. The mixture is stored in an aerosol spray type container at room temperature and drops to −41 °C (−42 °F) when dispensed. The mixture is often dispensed into a straw with a cotton-tipped swab.

Robotics is the branch of mechanical engineering, electrical engineering and computer science that deals with the design, construction, operation, and application of robots,[1] as well as computer systems for their control, sensory feedback, and information processing. These technologies deal with automated machines that can take the place of humans in dangerous environments or manufacturing processes, or resemble humans in appearance, behaviour, and or cognition. Many of today's robots are inspired by nature, contributing to the field of bio-inspired robotics. The concept of creating machines that can operate autonomously dates back to classical times, but research into the functionality and potential uses of robots did not grow substantially until the 20th century.[2] Throughout history, it has been frequently assumed that robots will one day be able to mimic human behavior and manage tasks in a human-like fashion. Today, robotics is a rapidly growing field, as technological advances continue; researching, designing, and building new robots serve various practical purposes, whether domestically, commercially, or militarily. Many robots are built to do jobs that are hazardous to people such as defusing bombs, finding survivors in unstable ruins, and exploring mines and shipwrecks. Robotics is also used in STEM (Science, Technology, Engineering, and Mathematics) as a teaching aid.
