A method for amplifying free nucleic acids (NAs) directly from one drop unpurified crude sample. The sample comprises nucleic acid fragments. The method includes (a) mixing an unpurified sample with a buffer to form an uniformly mixed solution; (b) adding the mixed solution to a tube then heating the tube to denature the proteins in the mixed solution, and cooling to room temperature; (c) subjecting he nucleic acid fragments in the mixture to a processing reaction required for adaptor-dependent PCR; (d) performing a ligation reaction between the processed nucleic acid fragments and adapters, forming nucleic acid fragments ligated with adapter in both ends, wherein the adapter is a complementary double-stranded nucleic acid (dsNA) fragment, one of which is an oligonucleotide with 5-phosphate and the other is an oligonucleotide with thymine (T) or uracil (U); and (e) performing the adapter-dependent PCR to the nucleic acid fragments in the mixed solution.

The invention provides methods for amplifying nucleic acids, particularly methods for reducing density-dependent GC bias and for reducing nucleic acid damage in a bridge amplification of a nucleic acid template. The invention also provides methods for evaluating the effect of reagents and/or additives on nucleic acid damage during bridge amplification of nucleic acid template strands. The methods are suited to solid phase amplification, for example, utilizing flow cells.
