what is The ELISA Kit？
ELISA stands for Enzyme Linked Immuno Sorbent, and to this day, the ELISA kit is the safest and quickest way to diagnose various types of infectious diseases in humans. The ELISA kit, in one of its many forms can also be used to diagnose various diseases in plants and animals as well. The ELISA test can similarly be regarded as the pregnancy test, because it pretty much works the same way. The most common use for the ELISA kit is the detection of antibodies and antigens in samples in the field of immunology. Apart from using the ELISA kit for toxicology tests that quickly detect the presence or absence of certain drugs cause.
Another field in which the ELISA kit has become increasingly important in the food industry. Industry experts use the ELISA kit for the search for various items that do not want to appear on certain products. For example, milk, tree nuts, peanuts, eggs and other ingredients to make similar cause allergic reactions, and a product that does not advertise with one or more of these elements test, tests performed using the ELISA kit. Apart from the fact that in the food industry and law enforcement or competitive ELISA, the kit widely known for his famous used to detect HIV and other viruses. One of the biggest advantages of using the ELISA kit, apart from the exact results is the low price of this product. The financial aspect, together with the short test phase, the ELISA kit to run into one of the most commonly used test methods in the world. Regardless of whether used in diagnostics, plant pathology or product quality control, the ELISA kit in the same way works.
When performing an ELISA test kit antigen is distributed on a surface. In the next step, an antibody that is specific to this test, the antigen is presented in a bind between the two compounds. The final steps are left, the antibody with an enzyme and then adding an insightful solution that helps the enzyme to convert a visible signal. This readable signal will reveal the exact amount of antigen in this specific sample. Since the ELISA test kit for the presence of antibodies and antigen shows, and so it can be used to determine the exact concentration of serum antibodies, it has become one of the most important tools in the correct recognition and diagnosis of HIV virus and also other viruses such as West Nile virus. The high sensitivity of the ELISA test kit has been presented many times that, compared with inspections carried out by using the available microscope.
Using ELISA kits both diagnosis and monitoring of infectious diseases like West Nile virus or HIV. The accuracy of the ELISA kits and the short time of reaction are its strongest selling points. ELISA kits are also very sensitive to specific antibodies and analytical systems to detect very small amounts of chemicals. The high sensitivity of the ELISA kits is due to the strong catalytic ability of enzymes. ELISA methods are also very selective because of the exceptional abilities of discriminatory antibodies. Concentration as low as parts per billion (ppb) can be detected. In addition, an ELISA kit very easy to use and the results are easy to understand.
Commercial uses of the ELISA kits are in high demand. Over-the-counter pregnancy tests use this principle by using monoclonal antibodies against the protein in the urine samples. Diabetes to monitor blood sugar levels can with the help of a mediator molecule interface, biological and electronic components of a sensor, the current results in a reading. Antibiotic residues in milk can be made using an ELISA kit, which inhibit the growth of a test organism can be monitored. ELISA kits are used in the field of food safety by the presence of salmonella. This test is used to predict Salmonella carrier status in cattle. ELISA kits have a huge impact on modern medicine.

what is Building Integrated Photovoltaics(BIPV)?
Solar panels are an increasingly familiar sight up and down the country, and now most people would be able to recognize if they saw her. But a new market segment within the solar industry, emerging markets, and this is Building Integrated Photovoltaics (BIPV). But what is BIPV you might ask, and how it works, compare the more common non-integrated solar cells?
BIPV refers to when photovoltaic materials are integrated into the construction of the building itself in the place of conventional building materials. For example, this may be in the roofing, facades, shading, or skylights. BIPV is able to be a source of strength for the building, as well as offering part of its construction.
Its most common use is in the construction of new buildings. The materials are generally more expensive than non-integrated solar panels, but these costs for new buildings compared to those of building materials that can replace them will be charged. BIPV can be retrofitted to existing buildings, but this is often more expensive than one built solar panels on an existing roof, as the original building materials have already been installed and paid for.
BIPV is an interesting perspective for architects, since it is a new element to the design and structure of the building. The photovoltaic cells in a wide range of colors that can come to the aesthetics of the building added. There are several known projects that have used BIPV technology. An example is the Zero Energy Media Wall in Beijing, the largest LED display in the world has. Here is the photovoltaic materials have been incorporated into the glass facade of the building, where they harvest solar energy during the day, and use it to the screen after dark, lights, mirror one day climatic cycle.
It is clear that BIPV can be a great source of innovation in the design of new buildings and can produce some impressive results from an architectural point of view. But it is for every day at home? If you are building a new house, or are interested in could build a awning for a patio, then you are for BIPV. Solar tiles can be factored into the planning phase, so instead of conventional building materials and provides your home with a source of renewable energy. But for the majority of people considering solar energy for homes, solar panels will still be the more likely option. That's because most people will upgrade to the increased costs of BIPV are not offset against building materials. It also includes retrofitting BIPV more work than installing solar panels, as the original roofing materials would have before the installation of solar tiles are removed in their place.

what is organic photovoltaic materials?
organic photovoltaic materials is a specialized semiconductor diode that converts visible light into direct current (DC) electricity. Some photovoltaic cells can convert the infrared (IR) or ultraviolet (UV) radiation in DC.Zajedničko feature of both small molecules and polymers (Figure 1) is used in photovoltaic systems is that they all have great sustav.Konjugirani conjugated system is formed in which carbon atoms covalently links with alternating single and double bonds, in other words to the chemical reactions of hydrocarbons. These electrons hydrocarbons PZ orbitals delocalize and form delocalized π orbital relationship with the π * antibonding π orbitals orbitalne.Delokalizirana the highest occupied molecular orbital (homo), and π * orbital of the lowest unoccupied molecular orbital (LUMO). Separation between Homo and the LUMO band is considered organic electronic materijala.Pojas is usually in the range of 1-4 eV.
When these materials absorb a photon, an excited state is created and limited to molecules or polymers lanca.Pobuđeno state area can be considered as an electron hole pair is connected by electrostatic interactions, ie excitons. In photovoltaic cells, excitons are broken up into free electrons hole pairs polja.Na effective force fields are set by creating a heterojunction between two different materials. Effective field excitons that break down causing an electron falls from conducting band absorber band for the implementation of the acceptor molecule.
