All these subjects have the involvement of physics in specific manner which gives a name interdisciplinary approach or trans-disciplinary approach. Now it is very important discussion at your level that how would you decide a subject which could be the most suitable and interesting for your career perspective. Try to screen the subject by having a detailed look on the course basket and then analyze which courses give you broader pace in terms of interpretation and further to develop the concept. Once you are done with this exercise start to explore the institute or universities for the better future. Here you are to explore the institutes based on certain academic criteria which are very important factors to shape up any career. First of all see the institutional accreditation and affiliation that is conferred by govt regulatory agencies -University Grant Commission, All India Council of Technical Education -AICTE.

As far as research implementation is concerned in physics related to natural sciences or life sciences it is very interesting to address the involvement of physics and give the kind of shape which appeals mass to upgrade the society which the ultimate goal. For an example DNA is the module of biological sciences but it has been given a model based on the chemistry and physics which is rather being explained as three dimensional (3D) model. Similarly bio-materials are very difficult to analyze due to the large dimension or mass where nano-material or chips are being designed with the help of physics. Therefore your basic knowledge in your subject become persistent for any type of investigation whether it is living material or inert material. So you have a bright future ahead with your basic degree in physics.
Good luck
