What is microinjections?

Microinjections are a technique used for delivering small quantities of substances or solutions directly to specific cells or tissues. It involves using a very fine needle and a microinjector to deliver the solution into the desired location. This technique is widely used in biological research, particularly in genetic engineering, cell studies, and drug testing. Microinjections can be performed on a variety of organisms, from bacteria and yeast to plants and animals, including mammals and humans. Some of the substances that can be delivered through microinjections include DNA, RNA, proteins, peptides, and small molecules. Advancements in technology have also enabled the development of more precise microinjection methods, such as single-cell microinjections and intracytoplasmic sperm injection, which have important applications in fields like assisted reproductive technology and developmental biology.
