XXIst century - a biological century follows by the last decade of XXth century - a computer age. During many decades of rapid scientific development, a new scientific branch was born and grew up too fast, it is bioinformatics. However, the concept and application of bioinformatics isn't known widely. So, in this article, author introduced concept bioinformatics and its applications in biotechnology, medicine and pharmacy, forensic biology

In Trang An polyclinics in Ha Noi, with ELISA technique, 35 healthy people (27 female aged 20-38, 8 male aged 25-37) undergone an examination of serum CA153-3 and 31 other healthy people (17 female aged 21-38, 14 male aged 22-41) an examination of resum CA125. The technique is complicated needing precaution and accuracy; for each examination, it is recommended a standard graphic with a standard sample determined antigen concentration. CA15-3 normal concentration is 2.37-18.17 U/ml, and CA125 is 7.17-38.37 U/ml

Immunology plays an important role in prevention, discovery, diagnosis and treatment. There are 4 major immunological techniques including ELISA (enzyme linked immuno-sorbent assay), ICA (immuno-chromatography assay), GLORIA (gold labeled optical read rapid immunoassay) and MCIA (membrane capture immunoassay). These techniques with the simple test devices such as test paper, test stick, test cassette provided the rapid results. The immunological techniques have been applying in emergency tests (myocardial infection, embolism, thrombosis, and occlusion), infection viral infection, allergy, cancer and drug abuse

The markers of cancer were generated from cells of cancer or metabolism or immunoresponse to the canceration. For the last 2 decades of 20th century, many markers of cancer used clinically thanks to the development of new clone antibody. By developing the molecular biology. Many genes of cancer, telomere, telomerase, survivin were considered as markers of cancer have been detected for the recent 20 years.

This paper introduced some differences of molecular biological techniques from microbiological techniques and some advantages of molecular biological techniques. They comprised fast and early detection, safety, convenient, effective, inexpensive techniques, allowance for diagnosis of causative agents that not able to culture, facilitate for prognosis and monitoring of the treatment. The molecular biological techniques showed its important role more and more and combined with microbiological technique to improve the diagnosis, treatment and prognosis

During transition years of 20th and 21st century, the molecular biology has had major progresses in the finding the nature of cancer's generation, early detection, prognosis and treatment of cancer. The molecular techniques were important breakthrough. The predominant achievement was to newly discover the role of telomere, telomerase and surviving in the cancer.

For more than past hundred years, Engels F. thought that the nature of life was protein. The human was decided by 2 factors, including genome and various influences of environment. The establishment of science of protein system (proteomics) is a break through of biology in 21st century.
Genomics ; Proteomics

Proteomics opened a complete new way in the medical and pharmaceutical sector. It helped detecting causes of unknown diseases, early diagnosing, contributing to optimal treatment of many diseases, and manufacturing new drugs as molecular mechanism. It is hoped that proteomics will be used to understand and treat cancer

In the 21st century, proteomics, a new science, appears in the biology. Proteomics studies the human protein, opens a new era of molecular pathology. The scientists suggest that the human being is determined by 2 factors: the genetic system or human genome and various influences of surrounding environment. From which, proteomics have been become the turning point of the biology at the beginning of 21st century.
