How can I get a good science project on electrophoresis?

Electrophoresis is the movement of an electrically charged substance under the influence of an electric field. This movement is due to the Lorentz force, which may be related to fundamental electrical properties of the body under study and the ambient electrical conditions by the equation given below. F is the Lorentz force, q is the charge carried by the body, E is the electric field [1]:\n\n. \nThe resulting electrophoretic migration is countered by forces of friction such that the rate of migration is constant in a constant and homogeneous electric field:\n\n \nWhere v is the velocity and f is the frictional coefficient.\n\n \nThe electrophoretic mobility μ is defined as followed.\n\n \nThe expression above applied only to ions at a concentration approaching 0 and in a non-conductive solvent. Polyionic molecules are surrounded by a cloud of counterions which alter the effective electric field applied on the ions to be separated. This render the previous expression a poor approximation of what really happens in an electrophoretic aparatus.\n\nThe mobility depends on both the particle properties (e.g., surface charge density and size) and solution properties (e.g., ionic strength, electric permittivity, and pH). For high ionic strengths, an approximate expression for the electrophoretic mobility is given by the Smoluchowski equation,\n\n, \nwhere ε is the dielectric constant of the liquid, ε0 is the permitivitty of free space, η is the viscosity of the liquid, and ζ is the zeta potential (i.e., surface potential) of the particle.\n\n[edit]\nApplications\nGel electrophoresis is an application of electrophoresis in molecular biology. The content of the buffers (solutions) and gels used to enhance viscosity greatly affects the mobility of macromolecules.

Yes, you need a lab to do this! If that wasn't clear to you, this may not be the best project to try to copy!\n\nWhy not have an idea of you own, something you can do with what you have at hand at home? You might learn something!

Do not go for the normal, typical projects that wind up at every science fair--the volcano, the planet mobile, etc.  Just do a project on something you are truly interested in.  Anything can be a science fair project:\n\nDoes expensive lipstick last longer than cheap lipstick?\nDo vegetables last longer on the counter or refrigerated?\nWhich hamburger molds first: McDonald's, Burger King's, or Hardee's?\nDo food packages really contain the amount (weight) of food they list on their packaging?\nCan people tell the difference between namebrand vs. generic shampoo, soda, candy, etc?

electrophoresis depends upon the charge carried by the different colloidal particles.As all colloidal particles tend to aggregate this method is far more suitable.\nHardy Schulz Rule:\n1) The oppositely charged ions are effective in causing the coagulation of colloidal particles.\n2) The coagulating power of a particle is directly proportional to the fourth power of the charge carried by the ion.\nAccording to these rules the dispersed phase and the dispersion medium can be easily separated.\nIn other methods the dispersed phase and dispersion medium are separated physically whereas in electrophoresis it is done chemically thereby giving it a greater efficiency.

get a good book\nlike the McGraw and Hill\nthats what we have in our Lab Chemistry class\nor go to the bonny eagle high school page and get the email for Helen Steele\nshe is a geneous i bet she could help you

I'm also doing an environmental project (school). I found lots of interesting stuff by asking the people around here. Try that but don't say it's your homework or something.

Electrophoresis is a process of seperation of molecules based on electric charge they possess using mild electric field in an electrolyte medium. Protein peptides for eg. can be separated by breaking the long protein chain using denaturing chemical such as beta-mercaptoethanol and treated with a detergent such as sodium dodycyl sulphate to render net negative charge to the molecules (peptides so broken). Now, sepration takesplace mainly on the basis of molecular weight of the peptide. U can use standard peptides/proteins to get a separation calibration curve. These are available commercially.

So where do you get ideas for biology science fair projects? The answer is from almost anywhere. The key is to start with a question that you would like to find an answer to and use the scientific method to help you answer it. When choosing a science fair project topic, make sure that you select a topic that you are interested in. Then narrow this topic down to a specific question.

Need more info in order to help you...what class level?...what field of chem?...writing project or lab demo?...what is an 'investigatory project'?\nPlease resubmit your question anew with as much info as possible so that we can offer reasonable suggestions...if you simply edit this one we cannot reply twice to same question.
