| Abstract | Molecular recognition properties of biodegradable photo-crosslinked networks based on poly(lactic acid) (PLA) and poly(ethylene glycol) (PEG) were evaluated. A biodegradable crosslinker, diacrylated PLA-PEG-PLA triblock copolymer was synthesized through the ring opening polymerization of D,L-lactide using hydrophilic PEG as a macroinitiator, followed by diacrylation of the end groups for the introduction of the polymerizable vinyl groups. The synthesis of acrylate end-capped macromers was characterized using FTIR and $^{1}$H NMR spectroscopic techniques. These macromers were used to prepare biodegradable molecularly imprinted polymers (MIPs) by photopolymerization with methacrylic acid (functional monomer) and theophylline (model template). Various polymers were prepared by changing the ratio of functional monomer to the crosslinking agent and the macromer concentration in order to obtain optimum conditions for MIP synthesis. The theophylline-imprinted polymer demonstrated higher rebinding capacity to theophylline than its corresponding non-imprinted polymer (NIP) and selectivity for theophylline over caffeine (similar structure molecule), suggesting that these polymer networks can potentially be used as biodegradable materials with specific molecular recognition properties. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
